# Forecast Validation & Continuous Improvement Implementation Summary
|
||||
|
||||
**Date**: November 18, 2025
|
||||
**Status**: ✅ Complete
|
||||
**Services Modified**: Forecasting, Orchestrator
|
||||
|
||||
---
|
||||
|
||||
## Overview
|
||||
|
||||
Successfully implemented a comprehensive 3-phase validation and continuous improvement system for the Forecasting Service. The system automatically validates forecast accuracy, handles late-arriving sales data, monitors performance trends, and triggers model retraining when needed.
|
||||
|
||||
---
|
||||
|
||||
## Phase 1: Daily Forecast Validation ✅
|
||||
|
||||
### Objective
|
||||
Implement daily automated validation of forecasts against actual sales data.
|
||||
|
||||
### Components Created
|
||||
|
||||
#### 1. Database Schema
|
||||
**New Table**: `validation_runs`
|
||||
- Tracks each validation execution
|
||||
- Stores comprehensive accuracy metrics (MAPE, MAE, RMSE, R², Accuracy %)
|
||||
- Records product and location performance breakdowns
|
||||
- Links to orchestration runs
|
||||
- **Migration**: `00002_add_validation_runs_table.py`
|
||||
|
||||
#### 2. Core Services
|
||||
**ValidationService** ([services/forecasting/app/services/validation_service.py](services/forecasting/app/services/validation_service.py))
|
||||
- `validate_date_range()` - Validates any date range
|
||||
- `validate_yesterday()` - Daily validation convenience method

|
||||
|
||||
**SalesClient** ([services/forecasting/app/services/sales_client.py](services/forecasting/app/services/sales_client.py))
|
||||
- Wrapper around shared Sales Service client
|
||||
- Fetches sales data with pagination support
|
||||
- Handles errors gracefully (returns empty list to allow validation to continue)
|
||||
|
||||
#### 3. API Endpoints

|
||||
3. **Event System** → Webhook-based notifications for real-time processing
|
||||
|
||||
### Gap Detection Logic
|
||||
```python
|
||||
# Find dates with forecasts
|
||||
forecast_dates = {f.forecast_date for f in forecasts}
|
||||
|
||||
# Find dates already validated
|
||||
validated_dates = {v.validation_date_start for v in validation_runs}
|
||||
|
||||
# Find gaps
|
||||
gap_dates = forecast_dates - validated_dates
|
||||
|
||||
# Group consecutive dates into ranges
|
||||
gaps = group_consecutive_dates(gap_dates)
|
||||
```
|
||||
|
||||

||||
|
||||
#### 1. Core Services
|
||||

|
||||
|
||||
#### 2. API Endpoints

|
||||
### Performance Thresholds
|
||||
```python
|
||||
MAPE_WARNING_THRESHOLD = 20.0 # Warning if MAPE > 20%
|
||||
MAPE_CRITICAL_THRESHOLD = 30.0 # Critical if MAPE > 30%
|
||||
MAPE_TREND_THRESHOLD = 5.0 # Alert if MAPE increases > 5%
|
||||
MIN_SAMPLES_FOR_ALERT = 5 # Minimum validations before alerting
|
||||
TREND_LOOKBACK_DAYS = 30 # Days to analyze for trends
|
||||
```
|
||||
|
||||
### Degradation Detection
|
||||
- Splits validation runs into first half and second half
|
||||
- Compares average MAPE between periods
|
||||
- Severity levels:
|
||||
- **None**: MAPE change ≤ 5%
|
||||
- **Medium**: 5% < MAPE change ≤ 10%
|
||||
- **High**: MAPE change > 10%
|
||||
|
||||
### Automatic Retraining Triggers
|
||||
1. **Poor Performance**: MAPE > 30% for any product
|
||||
2. **Degradation**: MAPE increased > 5% over 30 days
|
||||
3. **Age-Based**: Model not updated in 30+ days
|
||||
4. **Manual**: Triggered via API by admin/owner
|
||||
|
||||
### Training Service Integration
|
||||
- Calls Training Service API to trigger retraining
|
||||
- Passes `tenant_id`, `inventory_product_id`, `reason`, `priority`
|
||||
- Tracks training job ID for monitoring
|
||||
- Returns status: triggered/failed/no_response

|
||||
## Business Impact
|
||||
|
||||
### Before Implementation
|
||||
- ❌ No systematic forecast validation
|
||||
- ❌ No visibility into model accuracy
|
||||
- ❌ Late sales data ignored
|
||||
- ❌ Manual model retraining decisions
|
||||
- ❌ No tracking of forecast quality over time
|
||||
- ❌ Trust in forecasts based on intuition
|
||||
|
||||
### After Implementation
|
||||

|
||||
## Technical Implementation Details
|
||||
|
||||
### Error Handling
|
||||
- All services use try/except with structured logging
|
||||
- Graceful degradation (validation continues if some forecasts fail)
|
||||
- Retry mechanism for failed validations
|
||||
- Transaction safety with rollback on errors
|
||||
|
||||
### Performance Optimizations
|
||||
- Bulk insertion for validation metrics
|
||||
- Pagination for large datasets
|
||||
- Efficient gap detection with set operations
|
||||
- Indexed queries for fast lookups
|
||||
- Async/await throughout for concurrency
|
||||
|
||||
### Security
|
||||
- Role-based access control (@require_user_role)
|
||||
- Tenant isolation (all queries scoped to tenant_id)
|
||||
- Input validation with Pydantic schemas
|
||||
- SQL injection prevention (parameterized queries)
|
||||
- Audit logging for all operations
|
||||
|
||||
### Testing Considerations
|
||||
- Unit tests needed for all services
|
||||
- Integration tests for workflow flows
|
||||
- Performance tests for bulk operations
|
||||
- End-to-end tests for orchestrator integration

|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Database Changes
|
||||
|
||||
### Tenant Settings Schema
|
||||
|
||||
**Before:**
|
||||
```json
|
||||
{
|
||||
"notification_settings": {
|
||||
"whatsapp_enabled": false,
|
||||
"whatsapp_phone_number_id": "",
|
||||
"whatsapp_access_token": "", // REMOVED
|
||||
"whatsapp_business_account_id": "", // REMOVED
|
||||
"whatsapp_api_version": "v18.0", // REMOVED
|
||||
"whatsapp_default_language": "es"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**After:**
|
||||
```json
|
||||
{
|
||||
"notification_settings": {
|
||||
"whatsapp_enabled": false,
|
||||
"whatsapp_phone_number_id": "", // Phone from shared account
|
||||
"whatsapp_display_phone_number": "", // NEW: Display format
|
||||
"whatsapp_default_language": "es"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Migration:** No SQL migration needed (JSONB is schema-less). Existing data will work with defaults.
|
||||
|
||||
---
|
||||
|
||||
## Cost Estimate
|
||||
|
||||
### WhatsApp Messaging Costs (Spain)
|
||||
|
||||
- **Per conversation:** €0.0319 - €0.0699
|
||||
- **Conversation window:** 24 hours
|
||||
- **User-initiated:** Free
|
||||
|
||||
### Monthly Estimate (10 Bakeries)
|
||||
|
||||
```
|
||||
5 POs per bakery per day × 10 bakeries × 30 days = 1,500 messages/month
|
||||
1,500 × €0.05 (avg) = €75/month
|
||||
```
|
||||
|
||||
### Setup Cost Savings
|
||||
|
||||
**Old Model (Per-Tenant):**
|
||||
- 10 bakeries × 1.5 hours × €50/hr = **€750 in setup time**
|
||||
|
||||
**New Model (Shared Account):**
|
||||
- Admin: 2 hours setup (one time)
|
||||
- Per bakery: 5 minutes × 10 = **€0 in bakery time**
|
||||
|
||||
**Savings:** €750 in bakery owner time + reduced support tickets
|
||||

|
||||
|
||||
## Monitoring & Maintenance
|
||||
|
||||
### Check Quality Rating (Weekly)
|
||||
|
||||
```bash
|
||||
curl -X GET "https://graph.facebook.com/v18.0/{PHONE_NUMBER_ID}" \
|
||||
-H "Authorization: Bearer {ACCESS_TOKEN}" \
|
||||
| jq '.quality_rating'
|
||||
```
|
||||
|
||||
**Quality Ratings:**
|
||||
- **GREEN** ✅ - All good
|
||||
- **YELLOW** ⚠️ - Review messaging patterns
|
||||
- **RED** ❌ - Fix immediately
|
||||
|
||||
### View Message Logs
|
||||
|
||||
```bash
|
||||
# Docker logs
|
||||
docker logs -f notification-service | grep whatsapp
|
||||
|
||||
# Database query
|
||||
SELECT tenant_id, recipient_phone, status, created_at, error_message
|
||||
FROM whatsapp_messages
|
||||
WHERE created_at > NOW() - INTERVAL '24 hours'
|
||||
ORDER BY created_at DESC;
|
||||
```
|
||||
|
||||
### Rotate Access Token (Every 60 Days)
|
||||
|
||||
1. Generate new token in Meta Business Manager
|
||||
2. Update `WHATSAPP_ACCESS_TOKEN` in `.env`
|
||||
3. Restart notification service
|
||||
4. Revoke old token
|
||||
|
||||
---
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Bakery doesn't receive WhatsApp messages
|
||||
|
||||
**Checklist:**
|
||||
1. ✅ WhatsApp enabled in tenant settings?
|
||||
2. ✅ Phone number assigned to tenant?
|
||||
3. ✅ Master credentials in environment variables?
|
||||
4. ✅ Template approved by Meta?
|
||||
5. ✅ Recipient phone in E.164 format (+34612345678)?
|
||||
|
||||
**Check logs:**
|
||||
```bash
|
||||
docker logs -f notification-service | grep -i "whatsapp\|error"
|
||||
```
|
||||
|
||||
### Phone assignment fails: "Already assigned"
|
||||
|
||||
Find which tenant has it:
|
||||
```bash
|
||||
curl http://localhost:8001/api/v1/admin/whatsapp/tenants | \
|
||||
jq '.[] | select(.phone_number_id == "YOUR_PHONE_ID")'
|
||||
```
|
||||
|
||||
Unassign first:
|
||||
```bash
|
||||
curl -X DELETE http://localhost:8001/api/v1/admin/whatsapp/tenants/{tenant_id}/unassign-phone
|
||||
```
|
||||
|
||||
### "WhatsApp master account not configured"
|
||||
|
||||
Ensure environment variables are set:
|
||||
```bash
|
||||
docker exec notification-service env | grep WHATSAPP
|
||||
```
|
||||
|
||||
Should show all variables (WABA ID, Access Token, Phone Number ID).
|
||||
|
||||

||||
- Found in: WhatsApp Manager → Settings → Business Info
|
||||
- Format: `987654321098765` (15 digits)
|
||||
- **Save this:** You'll need it for environment variables
|
||||
|
||||
---
|
||||
|
||||
## Step 3: Add Phone Numbers
|
||||
|
||||
### 3.1 Add Your First Phone Number
|
||||
|
||||
**Option A: Use Your Own Phone Number** (Recommended for testing)
|
||||
|
||||
1. In WhatsApp Manager → **Phone Numbers**
|
||||
2. Click **Add Phone Number**
|
||||
3. Enter phone number in E.164 format: `+34612345678`

|
||||
2. Click **Get a free phone number**
|
||||
3. Choose country: Spain (+34)

||||
5. Note: Free numbers have limitations:
|
||||
- Can't be ported to other accounts
|
||||
- Limited to 1,000 conversations/day
|
||||
- Good for pilot, not production
|
||||
|
||||
### 3.2 Add Additional Phone Numbers (For Pilot Bakeries)
|
||||
|
||||
Repeat the process to add 10 phone numbers total (one per bakery).
|
||||
|
||||
**Tips:**
|
||||
- Use virtual phone number services (Twilio, Plivo, etc.)
|
||||
- Cost: ~€5-10/month per number
|
||||
- Alternative: Request Meta phone numbers (via support ticket)
|
||||
|
||||
**Request Phone Number Limit Increase:**
|
||||
|
||||
If you need more than 2 phone numbers:
|
||||
|
||||

|
||||
2. Request: "Increase phone number limit to 10 for pilot program"
|
||||
3. Provide business justification
|
||||
4. Wait 1-2 days for approval
|
||||

|
||||
|
||||
## Step 4: Create System User & Access Token
|
||||
|
||||
### 4.1 Create System User
|
||||
|
||||
**Why:** System Users provide permanent access tokens (don't expire every 60 days).
|
||||
|
||||
1. In Business Settings → **Users** → **System Users**
|
||||
2. Click **Add**
|
||||
3. Enter details:
|
||||
- Name: "WhatsApp API Service"
|
||||
- Role: **Admin**
|
||||
4. Click **Create System User**
|
||||
|
||||
### 4.2 Generate Access Token
|
||||
|
||||
1. Select the system user you just created
|
||||
2. Click **Add Assets**
|
||||
3. Choose **WhatsApp Accounts**
|
||||
4. Select your WhatsApp Business Account
|
||||
5. Grant permissions:
|
||||
- ✅ Manage WhatsApp Business Account
|
||||
- ✅ Manage WhatsApp Business Messaging
|
||||
- ✅ Read WhatsApp Business Insights
|
||||
6. Click **Generate New Token**
|
||||
7. Select token permissions:
|
||||
- ✅ `whatsapp_business_management`
|
||||
- ✅ `whatsapp_business_messaging`
|
||||
8. Click **Generate Token**
|
||||
9. **IMPORTANT:** Copy the token immediately
|
||||
- Format: `EAAxxxxxxxxxxxxxxxxxxxxxxxx` (long string)
|
||||
- **Save this securely:** You can't view it again!
|
||||
|
||||
**Token Security:**
|
||||
```bash
|
||||
# Good: Use environment variable
|
||||
WHATSAPP_ACCESS_TOKEN=EAAxxxxxxxxxxxxx
|
||||
|
||||
# Bad: Hardcode in source code
|
||||
# token = "EAAxxxxxxxxxxxxx" # DON'T DO THIS!
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Step 5: Create Message Templates
|
||||
|
||||
WhatsApp requires pre-approved templates for business-initiated messages.
|
||||
|
||||
### 5.1 Create PO Notification Template
|
||||
|
||||
1. In WhatsApp Manager → **Message Templates**
|
||||
2. Click **Create Template**
|
||||
3. Fill in template details:
|
||||
|
||||
```
|
||||

|
||||
|
||||
Message Body:

|
||||
Parameters:
|
||||

|
||||
```
|
||||
|
||||
4. Click **Submit for Approval**
|
||||
|
||||
**Approval Time:**
|
||||
- Typical: 15 minutes to 2 hours
|
||||
- Complex templates: Up to 24 hours
|
||||
- If rejected: Review feedback and resubmit
|
||||
|
||||
### 5.2 Check Template Status
|
||||
|
||||
**Via UI:**
|
||||
```
|
||||
WhatsApp Manager → Message Templates → Filter by Status
|
||||
```
|
||||
|
||||
**Via API:**
|
||||
```bash
|
||||
curl "https://graph.facebook.com/v18.0/{WABA_ID}/message_templates?fields=name,status,language" \
|
||||
-H "Authorization: Bearer {ACCESS_TOKEN}" | jq

- `PENDING` - Under review
|
||||
- `APPROVED` - Ready to use
|
||||
- `REJECTED` - Review feedback and fix

|
||||
|
||||
### 5.3 Create Additional Templates (Optional)
|
||||
|
||||
For inventory alerts, production alerts, etc.:
|
||||
|
||||
```
|
||||
Template Name: low_stock_alert
|
||||
Category: UTILITY
|
||||
Language: Spanish (es)
|
||||
Message:
|
||||
⚠️ Alerta: El ingrediente {{1}} tiene stock bajo.
|
||||
Cantidad actual: {{2}} {{3}}.
|
||||
Punto de reorden: {{4}} {{5}}.
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Step 6: Configure Webhooks (For Status Updates)
|
||||
|
||||
### 6.1 Create Webhook Endpoint
|
||||
|
||||
Webhooks notify you of message delivery status, read receipts, etc.
|
||||
|
||||
**Your webhook endpoint:**
|
||||
```
|
||||
https://your-domain.com/api/v1/whatsapp/webhook
|
||||
```
|
||||
|
||||
**Implemented in:** `services/notification/app/api/whatsapp_webhooks.py`
|
||||
|
||||
### 6.2 Register Webhook with Meta
|
||||
|
||||
1. In WhatsApp Manager → **Configuration**
|
||||
2. Click **Edit** next to Webhook
|
||||
3. Enter details:
|
||||
```
|
||||
Callback URL: https://your-domain.com/api/v1/whatsapp/webhook
|
||||
Verify Token: random-secret-token-here
|
||||
```
|
||||
4. Click **Verify and Save**
|
||||
|
||||
**Meta will send GET request to verify:**
|
||||
```
|
||||
GET /api/v1/whatsapp/webhook?hub.verify_token=YOUR_TOKEN&hub.challenge=XXXXX
|
||||
```
|
||||
|
||||
**Your endpoint must respond with:** `hub.challenge` value
|
||||
|
||||
### 6.3 Subscribe to Webhook Events
|
||||
|
||||
Select events to receive:
|
||||
|
||||
- ✅ `messages` - Incoming messages (for replies)
|
||||
- ✅ `message_status` - Delivery, read receipts
|
||||
- ✅ `message_echoes` - Sent message confirmations
|
||||
|
||||
**Environment Variable:**
|
||||
```bash
|
||||
WHATSAPP_WEBHOOK_VERIFY_TOKEN=random-secret-token-here
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Step 7: Configure Environment Variables
|
||||
|
||||
### 7.1 Collect All Credentials
|
||||
|
||||
You should now have:
|
||||
|
||||

|
||||
- Example: `EAAxxxxxxxxxxxxxxxxxxxxxxxx`
|
||||

|
||||
|
||||
3. ✅ **Phone Number ID** (default/fallback)
|
||||
- Example: `123456789012345`
|
||||
- Where: WhatsApp Manager → Phone Numbers
|
||||
|
||||
4. ✅ **Webhook Verify Token** (you chose this)
|
||||
- Example: `my-secret-webhook-token-12345`
|
||||
|
||||
### 7.2 Update Notification Service Environment
|
||||
|
||||
**File:** `services/notification/.env`
|
||||
|
||||
```bash
|
||||
# ================================================================
|
||||
# WhatsApp Business Cloud API Configuration
|
||||
# ================================================================
|
||||
|
||||
# Master WhatsApp Business Account ID (15 digits)
|
||||
WHATSAPP_BUSINESS_ACCOUNT_ID=987654321098765
|
||||
|
||||
# System User Access Token (starts with EAA)
|
||||
WHATSAPP_ACCESS_TOKEN=EAAxxxxxxxxxxxxxxxxxxxxxxxx
|
||||
|
||||
# Default Phone Number ID (15 digits) - fallback if tenant has none assigned
|
||||
WHATSAPP_PHONE_NUMBER_ID=123456789012345
|
||||
|
||||
# WhatsApp Cloud API Version
|
||||
WHATSAPP_API_VERSION=v18.0
|
||||
|
||||
# Enable/disable WhatsApp notifications globally
|
||||
ENABLE_WHATSAPP_NOTIFICATIONS=true
|
||||
|
||||
# Webhook verification token (random secret you chose)
|
||||
WHATSAPP_WEBHOOK_VERIFY_TOKEN=my-secret-webhook-token-12345
|
||||
```
|
||||
|
||||
### 7.3 Restart Services
|
||||
|
||||
```bash
|
||||
# Docker Compose
|
||||
docker-compose restart notification-service
|
||||
|
||||
# Kubernetes
|
||||
kubectl rollout restart deployment/notification-service
|
||||
|
||||
# Or rebuild
|
||||
docker-compose up -d --build notification-service
|
||||
```
|

||||
"quality_rating": "GREEN",
|
||||
"id": "123456789012345"
|
||||
}

### 8.2 Test Sending a Message
|
||||
|
||||
**Via API:**
|
||||
|
||||
```bash
|
||||
curl -X POST "https://graph.facebook.com/v18.0/{PHONE_NUMBER_ID}/messages" \
|
||||
-H "Authorization: Bearer {ACCESS_TOKEN}" \

|
||||
]
|
||||
}
|

|
||||
```
|
||||
|
||||
**Check WhatsApp on recipient's phone!**
|
||||
|
||||
### 8.3 Test via Notification Service
|
||||
|
||||
**Trigger PO notification:**
|
||||
|
||||
```bash
|
||||
curl -X POST http://localhost:8002/api/v1/whatsapp/send \
|
||||
-H "Content-Type: application/json" \

||||
### 9.3 Verify Assignments
|
||||
|
||||
```bash
|
||||
# Check all assignments
|
||||
curl http://localhost:8001/api/v1/admin/whatsapp/tenants | jq
|
||||
|
||||
# Should show each tenant with assigned phone
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Step 10: Monitor & Maintain
|
||||
|
||||
### 10.1 Monitor Quality Rating
|
||||
|
||||
WhatsApp penalizes low-quality messaging. Check your quality rating weekly:
|
||||
|
||||
```bash
|
||||
curl -X GET "https://graph.facebook.com/v18.0/{PHONE_NUMBER_ID}" \
|
||||
-H "Authorization: Bearer {ACCESS_TOKEN}" \
|
||||
| jq '.quality_rating'
|
||||
```
|
||||
|
||||
**Quality Ratings:**
|
||||
- **GREEN** ✅ - All good, no restrictions
|
||||
- **YELLOW** ⚠️ - Warning, review messaging patterns
|
||||
- **RED** ❌ - Restricted, fix issues immediately
|
||||
|
||||
**Common Issues Leading to Low Quality:**
|
||||
- High block rate (users blocking your number)
|
||||
- Sending to invalid phone numbers
|
||||
- Template violations (sending promotional content in UTILITY templates)
|
||||
- User reports (spam complaints)
|
||||
|
||||
### 10.2 Check Message Costs
|
||||
|
||||
```bash
|
||||
# View billing in Meta Business Manager
|
||||
Business Settings → Payments → WhatsApp Business API
|
||||
```
|
||||
|
||||
**Cost per Conversation (Spain):**
|
||||
- Business-initiated: €0.0319 - €0.0699
|
||||
- User-initiated: Free (24hr window)
|
||||
|
||||
**Monthly Estimate (10 Bakeries):**
|
||||
- 5 POs per day per bakery = 50 messages/day
|
||||
- 50 × 30 days = 1,500 messages/month
|
||||
- 1,500 × €0.05 = **~€75/month**
|
||||
|
||||
### 10.3 Rotate Access Token (Every 60 Days)
|
||||
|
||||
Even though system user tokens are "permanent," rotate for security:
|
||||
|
||||
1. Generate new token (Step 4.2)
|
||||
2. Update environment variable
|
||||
3. Restart notification service
|
||||
4. Revoke old token
|
||||
|
||||
**Set reminder:** Calendar alert every 60 days
|
||||
|
||||
---
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Issue: Business verification stuck
|
||||
|
||||
**Solution:**
|
||||
- Check Business Manager → Security Center
|
||||
- Common reasons:
|
||||
- Documents unclear/incomplete
|
||||
- Business name mismatch with documents
|
||||
- Banned domain/business
|
||||
- Contact Meta Business Support if > 5 days
|
||||
|
||||
### Issue: Phone number verification fails
|
||||
|
||||
**Error:** "This phone number is already registered with WhatsApp"
|
||||
|
||||
**Solution:**
|
||||
- Number is used for personal WhatsApp
|
||||
- You must use a different number OR
|
||||
- Delete personal WhatsApp account (this is permanent!)
|
||||
|
||||
### Issue: Template rejected
|
||||
|
||||
**Common Rejection Reasons:**
|
||||
1. **Contains promotional content in UTILITY template**
|
||||
- Fix: Remove words like "offer," "sale," "discount"
|
||||
- Use MARKETING category instead
|
||||
|
||||
2. **Missing variable indicators**
|
||||
- Fix: Ensure {{1}}, {{2}}, {{3}} are clearly marked
|
||||
- Provide good example values
|
||||
|
||||
3. **Unclear purpose**
|
||||
- Fix: Add context in template description
|
||||
- Explain use case clearly
|
||||
|
||||
**Resubmit:** Edit template and click "Submit for Review" again
|
||||
|
||||
### Issue: "Invalid OAuth access token"
|
||||
|
||||
**Solutions:**
|
||||
1. Token expired → Generate new one (Step 4.2)
|
||||
2. Wrong token → Copy correct token from System User
|
||||
3. Token doesn't have permissions → Regenerate with correct scopes
|
||||
|
||||
### Issue: Webhook verification fails
|
||||
|
||||
**Error:** "The URL couldn't be validated. Callback verification failed"
|
||||
|
||||
**Checklist:**
|
||||
- [ ] Endpoint is publicly accessible (not localhost)
|
||||
- [ ] Returns `200 OK` status
|
||||
- [ ] Returns the `hub.challenge` value exactly
|
||||
- [ ] HTTPS enabled (not HTTP)
|
||||
- [ ] Verify token matches environment variable
|
||||
|
||||
**Test webhook manually:**
|
||||
```bash
|
||||
curl "https://your-domain.com/api/v1/whatsapp/webhook?hub.verify_token=YOUR_TOKEN&hub.challenge=12345"
|
||||
# Should return: 12345
|
||||
```
|
||||
|
||||

|
||||
|

# WhatsApp Shared Account Model - Implementation Guide
|
||||
|
||||
## Overview
|
||||
|
||||
This guide documents the **Shared WhatsApp Business Account** implementation for the bakery-ia pilot program. This model simplifies WhatsApp setup by using a single master WhatsApp Business Account with phone numbers assigned to each bakery tenant.
|
||||
|
||||
---
|
||||
|
||||
## Architecture
|
||||
|
||||

|
||||

|
||||
|
||||
## Technical Implementation
|
||||
|
||||
### Backend Changes
|
||||
|
||||
#### 1. Tenant Settings Model
|
||||
|
||||
**File:** `services/tenant/app/models/tenant_settings.py`
|
||||
|
||||
**Changed:**
|
||||
```python
|
||||
# OLD (Per-Tenant Credentials)
|
||||
notification_settings = {
|
||||
"whatsapp_enabled": False,
|
||||
"whatsapp_phone_number_id": "",
|
||||
"whatsapp_access_token": "", # REMOVED
|
||||
"whatsapp_business_account_id": "", # REMOVED
|
||||
"whatsapp_api_version": "v18.0", # REMOVED
|
||||
"whatsapp_default_language": "es"
|
||||
}
|
||||
|
||||
# NEW (Shared Account)
|
||||
notification_settings = {
|
||||
"whatsapp_enabled": False,
|
||||
"whatsapp_phone_number_id": "", # Phone # from shared account
|
||||
"whatsapp_display_phone_number": "", # Display format "+34 612 345 678"
|
||||
"whatsapp_default_language": "es"
|
||||
}
|
||||
```
|
||||
|
||||
#### 2. WhatsApp Business Service
|
||||
|
||||
**File:** `services/notification/app/services/whatsapp_business_service.py`
|
||||
|
||||
**Changed `_get_whatsapp_credentials()` method:**
|
||||
|
||||
```python
|
||||
async def _get_whatsapp_credentials(self, tenant_id: str) -> Dict[str, str]:
|
||||
"""
|
||||
Uses global master account credentials with tenant-specific phone number
|
||||
"""
|
||||
# Always use global master account
|
||||
access_token = self.global_access_token
|
||||
business_account_id = self.global_business_account_id
|
||||
phone_number_id = self.global_phone_number_id # Default
|
||||
|
||||
# Fetch tenant's assigned phone number
|
||||
if self.tenant_client:
|
||||
notification_settings = await self.tenant_client.get_notification_settings(tenant_id)
|
||||
if notification_settings and notification_settings.get('whatsapp_enabled'):
|
||||
tenant_phone_id = notification_settings.get('whatsapp_phone_number_id', '')
|
||||
if tenant_phone_id:
|
||||
phone_number_id = tenant_phone_id # Use tenant's phone
|
||||
|
||||
return {
|
||||
'access_token': access_token,
|
||||
'phone_number_id': phone_number_id,
|
||||
'business_account_id': business_account_id
|
||||
}
|
||||
```
|
||||
|
||||
**Key Change:** Always uses global credentials, but selects the phone number based on tenant assignment.
|
||||
|
||||
#### 3. Phone Number Management API
|
||||
|
||||
**New File:** `services/tenant/app/api/whatsapp_admin.py`
|
||||
|
||||
**Endpoints:**
|
||||
|
||||
| Method | Endpoint | Description |
|
||||
|--------|----------|-------------|
|
||||
| GET | `/api/v1/admin/whatsapp/phone-numbers` | List available phone numbers from master WABA |
|
||||
| GET | `/api/v1/admin/whatsapp/tenants` | List all tenants with WhatsApp status |
|
||||
| POST | `/api/v1/admin/whatsapp/tenants/{id}/assign-phone` | Assign phone to tenant |
|
||||
| DELETE | `/api/v1/admin/whatsapp/tenants/{id}/unassign-phone` | Remove phone assignment |
|
||||
|
||||
**Example: Assign Phone Number**
|
||||
|
||||
```bash
|
||||
curl -X POST http://localhost:8001/api/v1/admin/whatsapp/tenants/{tenant_id}/assign-phone \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"phone_number_id": "123456789012345",
|
||||
"display_phone_number": "+34 612 345 678"
|
||||
}'
|
||||
```
|
||||
|
||||
**Response:**
|
||||
```json
|
||||
{
|
||||
"success": true,
|
||||
"message": "Phone number +34 612 345 678 assigned to tenant 'Panadería San Juan'",
|
||||
"tenant_id": "uuid-here",
|
||||
"phone_number_id": "123456789012345",
|
||||
"display_phone_number": "+34 612 345 678"
|
||||
}
|
||||
```

## Setup Instructions
|
||||
|
||||
### Step 1: Create Master WhatsApp Business Account (One-Time)
|
||||
|
||||
**Prerequisites:**
|
||||
- Meta/Facebook Business account
|
||||
- Verified business
|
||||
- Phone number(s) to register
|
||||
|
||||
**Instructions:**
|
||||
|
||||
1. **Create WhatsApp Business Account**
|
||||
- Go to [Meta Business Suite](https://business.facebook.com)
|
||||
- Add WhatsApp product
|
||||
- Complete business verification (1-3 days)
|
||||
|
||||
2. **Add Phone Numbers**
|
||||
- Add at least 10 phone numbers (one per pilot bakery)
|
||||
- Verify each phone number
|
||||
- Note: You can request up to 120 phone numbers per WABA
|
||||
|
||||
3. **Create Message Templates**
|
||||
- Create `po_notification` template:
|
||||
```
|
||||
Category: UTILITY
|
||||
Language: Spanish (es)
|
||||
Message: "Hola {{1}}, has recibido una nueva orden de compra {{2}} por un total de {{3}}."
|
||||
```
|
||||
- Submit for approval (15 min - 24 hours)
|
||||
|
||||
4. **Get Master Credentials**
|
||||
- Business Account ID: From WhatsApp Manager settings
|
||||
- Access Token: Create System User or use temporary token
|
||||
- Phone Number ID: Listed in phone numbers section
|
||||
|
||||
### Step 2: Configure Environment Variables
|
||||
|
||||
**File:** `services/notification/.env`
|
||||
|
||||
```bash
|
||||
# Master WhatsApp Business Account Credentials
|
||||
WHATSAPP_BUSINESS_ACCOUNT_ID=987654321098765
|
||||
WHATSAPP_ACCESS_TOKEN=EAAxxxxxxxxxxxxxxxxxxxxxxxxxx
|
||||
WHATSAPP_PHONE_NUMBER_ID=123456789012345 # Default/fallback phone
|
||||
WHATSAPP_API_VERSION=v18.0
|
||||
ENABLE_WHATSAPP_NOTIFICATIONS=true
|
||||
WHATSAPP_WEBHOOK_VERIFY_TOKEN=random-secret-token-here
|
||||
```
|
||||
|
||||
**Security Notes:**
|
||||
- Store `WHATSAPP_ACCESS_TOKEN` securely (use secrets manager in production)
|
||||
- Rotate token every 60 days
|
||||
- Use System User token (not temporary token) for production
|
||||
|
||||
### Step 3: Assign Phone Numbers to Tenants
|
||||
|
||||
**Via Admin UI:**
|
||||
|
||||
1. Access admin page: `http://localhost:5173/app/admin/whatsapp`
|
||||
2. See list of tenants
|
||||
3. For each tenant:
|
||||
- Select phone number from dropdown
|
||||
- Click assign
|
||||
- Verify green checkmark appears
|
||||
|
||||
**Via API:**
|
||||
|
||||
```bash
|
||||
# Assign phone to tenant
|
||||
curl -X POST http://localhost:8001/api/v1/admin/whatsapp/tenants/{tenant_id}/assign-phone \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"phone_number_id": "123456789012345",
|
||||
"display_phone_number": "+34 612 345 678"
|
||||
}'
|
||||
```
|
||||
|
||||
### Step 4: Test Notifications
|
||||
|
||||
**Enable WhatsApp for a Tenant:**
|
||||
|
||||
1. Login as bakery owner
|
||||
2. Go to Settings → Notifications
|
||||
3. Toggle WhatsApp ON
|
||||
4. Verify phone number is displayed
|
||||
5. Save settings
|
||||
|
||||
**Trigger Test Notification:**
|
||||
|
||||
```bash
|
||||
# Create a purchase order (will trigger WhatsApp notification)
|
||||
curl -X POST http://localhost:8003/api/v1/orders/purchase-orders \
|
||||
-H "Content-Type: application/json" \
|
||||
-H "X-Tenant-ID: {tenant_id}" \
|
||||
-d '{
|
||||
"supplier_id": "uuid",
|
||||
"items": [...]
|
||||
}'
|
||||
```
|
||||
|
||||
**Verify:**
|
||||
- Check notification service logs: `docker logs -f notification-service`
|
||||
- Supplier should receive WhatsApp message from assigned phone number
|
||||
- Message status tracked in `whatsapp_messages` table
|
||||
|
||||

|
||||
|
||||
## Monitoring & Operations
|
||||
|
||||
### Check Phone Number Usage
|
||||
|
||||
```bash
|
||||
# List all tenants with assigned phone numbers
|
||||
curl http://localhost:8001/api/v1/admin/whatsapp/tenants | jq
|
||||
```
|
||||
|
||||
### View WhatsApp Message Logs
|
||||
|
||||
```sql
|
||||
-- In notification database
|
||||
SELECT
|
||||
tenant_id,
|
||||
recipient_phone,
|
||||
template_name,
|
||||
status,
|
||||
created_at,
|
||||
error_message
|
||||
FROM whatsapp_messages
|
||||
WHERE created_at > NOW() - INTERVAL '24 hours'
|
||||
ORDER BY created_at DESC;
|
||||
```
|
||||
|
||||
### Monitor Meta Rate Limits
|
||||
|
||||
WhatsApp Cloud API has the following limits:
|
||||
|
||||
| Metric | Limit |
|
||||
|--------|-------|
|
||||
| Messages per second | 80 |
|
||||
| Messages per day (verified) | 100,000 |
|
||||
| Messages per day (unverified) | 1,000 |
|
||||
| Conversations per 24h | Unlimited (pay per conversation) |
|
||||
|
||||
**Check Quality Rating:**
|
||||
|
||||
```bash
|
||||
curl -X GET "https://graph.facebook.com/v18.0/{PHONE_NUMBER_ID}" \
|
||||
-H "Authorization: Bearer {ACCESS_TOKEN}" \
|
||||
| jq '.quality_rating'
|
||||
```
|
||||
|
||||
**Quality Ratings:**
|
||||
- **GREEN** - No issues, full limits
|
||||
- **YELLOW** - Warning, limits may be reduced
|
||||
- **RED** - Quality issues, severely restricted

## Migration from Per-Tenant to Shared Account
|
||||
|
||||
If you have existing tenants with their own credentials:
|
||||
|
||||
### Automatic Migration Script
|
||||
|
||||
```python
|
||||
# services/tenant/scripts/migrate_to_shared_account.py
|
||||
"""
|
||||
Migrate existing tenant WhatsApp credentials to shared account model
|
||||
"""
|
||||
|
||||
import asyncio
|
||||
from sqlalchemy import select
|
||||
from app.core.database import database_manager
|
||||
from app.models.tenant_settings import TenantSettings
|
||||
|
||||
async def migrate():
|
||||
async with database_manager.get_session() as session:
|
||||
# Get all tenant settings
|
||||
result = await session.execute(select(TenantSettings))
|
||||
all_settings = result.scalars().all()
|
||||
|
||||
for settings in all_settings:
|
||||
notification_settings = settings.notification_settings
|
||||
|
||||
# If tenant has old credentials, preserve phone number ID
|
||||
if notification_settings.get('whatsapp_access_token'):
|
||||
phone_id = notification_settings.get('whatsapp_phone_number_id', '')
|
||||
|
||||
# Update to new schema
|
||||
notification_settings['whatsapp_phone_number_id'] = phone_id
|
||||
notification_settings['whatsapp_display_phone_number'] = '' # Admin will set
|
||||
|
||||
# Remove old fields
|

notification_settings.pop('whatsapp_access_token', None)
|
||||
notification_settings.pop('whatsapp_business_account_id', None)
|
||||
notification_settings.pop('whatsapp_api_version', None)
|
||||
|
||||
settings.notification_settings = notification_settings
|
||||
|
||||
print(f"Migrated tenant: {settings.tenant_id}")
|
||||
|
||||
await session.commit()
|
||||
print("Migration complete!")
|
||||
|
||||
if __name__ == "__main__":
|
||||
asyncio.run(migrate())
|
||||
```
|
||||

|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Issue: Tenant doesn't receive WhatsApp messages
|
||||
|
||||
**Checklist:**
|
||||
1. ✅ WhatsApp enabled in tenant settings?
|
||||
2. ✅ Phone number assigned to tenant?
|
||||
3. ✅ Master credentials configured in environment?
|
||||
4. ✅ Template approved by Meta?
|
||||
5. ✅ Recipient phone number in E.164 format (+34612345678)?
|
||||
|
||||
**Check Logs:**
|
||||
|
||||
```bash
|
||||
# Notification service logs
|
||||
docker logs -f notification-service | grep whatsapp
|
||||
|
||||
# Look for:
|
||||
# - "Using tenant-assigned WhatsApp phone number"
|
||||
# - "WhatsApp template message sent successfully"
|
||||
# - Any error messages
|
||||
```
|
||||
|
||||
### Issue: Phone number assignment fails
|
||||
|
||||
**Error:** "Phone number already assigned to another tenant"
|
||||
|
||||
**Solution:**
|
||||
```bash
|
||||
# Find which tenant has the phone number
|
||||
curl http://localhost:8001/api/v1/admin/whatsapp/tenants | \
|
||||
jq '.[] | select(.phone_number_id == "123456789012345")'
|
||||
|
||||
# Unassign from old tenant first
|
||||
curl -X DELETE http://localhost:8001/api/v1/admin/whatsapp/tenants/{old_tenant_id}/unassign-phone
|
||||
```
|
||||
|
||||
### Issue: "WhatsApp master account not configured"
|
||||
|
||||
**Solution:**
|
||||
|
||||
Ensure environment variables are set:
|
||||
|
||||
```bash
|
||||
# Check if variables exist
|
||||
docker exec notification-service env | grep WHATSAPP
|
||||
|
||||
# Should show:
|
||||
# WHATSAPP_BUSINESS_ACCOUNT_ID=...
|
||||
# WHATSAPP_ACCESS_TOKEN=...
|
||||
# WHATSAPP_PHONE_NUMBER_ID=...
|
||||
```
|
||||
|
||||
### Issue: Template not found
|
||||
|
||||
**Error:** "Template po_notification not found"
|
||||
|
||||
**Solution:**
|
||||
|
||||
1. Create template in Meta Business Manager
|
||||
2. Wait for approval (check status):
|
||||
```bash
|
||||
curl -X GET "https://graph.facebook.com/v18.0/{WABA_ID}/message_templates" \
|
||||
-H "Authorization: Bearer {TOKEN}" \
|
||||
| jq '.data[] | select(.name == "po_notification")'
|
||||
```
|
||||
3. Ensure template language matches tenant's `whatsapp_default_language`
|
||||

## Cost Analysis
|
||||
|
||||
### WhatsApp Business API Pricing (as of 2024)
|
||||
|
||||
**Meta Pricing:**
|
||||
- **Business-initiated conversations:** €0.0319 - €0.0699 per conversation (Spain)
|
||||
- **User-initiated conversations:** Free (24-hour window)
|
||||
- **Conversation window:** 24 hours
|
||||
|
||||
**Monthly Cost Estimate (10 Bakeries):**
|
||||
- Assume 5 PO notifications per bakery per day
|
||||
- 5 × 10 bakeries × 30 days = 1,500 messages/month
|
||||
- Cost: 1,500 × €0.05 = **€75/month**
|
||||
|
||||
**Shared Account vs. Individual Accounts:**
|
||||
|
||||
| Model | Setup Time | Monthly Cost | Support Burden |
|
||||
|-------|------------|--------------|----------------|
|
||||
| Individual Accounts | 1-2 hrs/bakery | €75 total | High |
|
||||
| Shared Account | 5 min/bakery | €75 total | Low |
|
||||
|
||||
**Savings:** Time savings = 10 hrs × €50/hr = **€500 in setup cost**
|
||||
|
||||
---
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
### Option 1: Template Management API
|
||||
|
||||
Automate template creation for new tenants:
|
||||
|
||||
```python
|
||||
async def create_po_template(waba_id: str, access_token: str):
|
||||
"""Programmatically create PO notification template"""
|
||||
url = f"https://graph.facebook.com/v18.0/{waba_id}/message_templates"
|
||||
payload = {
|
||||
"name": "po_notification",
|
||||
"language": "es",
|
||||
"category": "UTILITY",
|
||||
"components": [{
|
||||
"type": "BODY",
|
||||
"text": "Hola {{1}}, has recibido una nueva orden de compra {{2}} por un total de {{3}}."
|
||||
}]
|
||||
}
|
||||
response = await httpx.post(url, headers={"Authorization": f"Bearer {access_token}"}, json=payload)
|
||||
return response.json()
|
||||
```
|
||||
|
||||
### Option 2: WhatsApp Embedded Signup
|
||||
|
||||
For scaling beyond pilot:
|
||||
|
||||
- Apply for Meta Business Solution Provider program
|
||||
- Implement OAuth-style signup flow
|
||||
- Users click "Connect WhatsApp" → auto-configured
|
||||
- Estimated implementation: 2-4 weeks
|
||||
|
||||
### Option 3: Tiered Pricing
|
||||
|
||||
```
|
||||
Basic Tier (Free):
|
||||
- Email notifications only
|
||||
|
||||
Standard Tier (€29/month):
|
||||
- Shared WhatsApp account
|
||||
- Pre-approved templates
|
||||
- Up to 500 messages/month
|
||||
|
||||
Enterprise Tier (€99/month):
|
||||
- Own WhatsApp Business Account
|
||||
- Custom templates
|
||||
- Unlimited messages
|
||||
- White-label phone number
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Security & Compliance
|
||||
|
||||
### Data Privacy
|
||||
|
||||
**GDPR Compliance:**
|
||||
- WhatsApp messages contain supplier contact info (phone numbers)
|
||||
- Ensure GDPR consent for sending notifications
|
||||
- Provide opt-out mechanism
|
||||
- Data retention: Messages stored for 90 days (configurable)
|
||||
|
||||
**Encryption:**
|
||||
- WhatsApp messages: End-to-end encrypted by Meta
|
||||
- Access tokens: Stored in environment variables (use secrets manager in production)
|
||||
- Database: Encrypt `notification_settings` JSON column
|
||||
|
||||
### Access Control
|
||||
|
||||
**Admin Access:**
|
||||
- Only platform admins can assign/unassign phone numbers
|
||||
- Implement role-based access control (RBAC)
|
||||
- Audit log for phone number assignments
|
||||
|
||||
```python
|
||||
# Example: Add admin check
|
||||
@router.post("/admin/whatsapp/tenants/{tenant_id}/assign-phone")
|
||||
async def assign_phone(tenant_id: UUID, current_user = Depends(require_admin_role)):
|
||||
# Only admins can access
|
||||
pass
|
||||
```
|
||||
|
||||
---
|
||||
|
||||

||||
```
|
||||
|
||||
### 10. Update handleDiscard function (line 316)

|
||||
|
||||

|
||||
|
||||
Change:
|

|
||||
```
|
||||
|
||||
To:
|
||||
```typescript
|
||||
onClick={activeTab === 'operations' || activeTab === 'notifications' ? handleSaveOperationalSettings : handleSaveConfig}
