# Multi-Tenant WhatsApp Configuration - IMPLEMENTATION COMPLETE ✅
## 🎉 Status: 100% Complete
All work has been successfully implemented and the frontend build passes without errors.
---
## Implementation Summary
This implementation allows each bakery (tenant) to configure their own WhatsApp Business credentials through the settings UI, enabling them to send notifications to suppliers using their own WhatsApp Business phone number.
### Key Features
**Per-Tenant Configuration**: Each tenant can configure their own WhatsApp Business credentials
**Fallback System**: Automatically falls back to global credentials if tenant settings not configured
**Multi-Language Support**: Full i18n support in Spanish, Basque, and English
**Secure Storage**: Credentials stored securely in PostgreSQL JSONB column
**User-Friendly UI**: Complete settings interface with helpful setup instructions
**Backward Compatible**: Existing deployments work without any changes
---
## What Was Implemented
### Phase 1: Backend - Tenant Service ✅
1. **Database Schema** ([services/tenant/app/models/tenant_settings.py](services/tenant/app/models/tenant_settings.py))
- Added `notification_settings` JSON column to store WhatsApp and email configuration
2. **Pydantic Schemas** ([services/tenant/app/schemas/tenant_settings.py](services/tenant/app/schemas/tenant_settings.py))
- Created `NotificationSettings` schema with validation
- Validates required fields when WhatsApp is enabled
3. **Service Layer** ([services/tenant/app/services/tenant_settings_service.py](services/tenant/app/services/tenant_settings_service.py))
- Added "notification" category support
- Mapped notification category to `notification_settings` column
4. **Database Migration** ([services/tenant/migrations/versions/002_add_notification_settings.py](services/tenant/migrations/versions/002_add_notification_settings.py))
- Created migration to add `notification_settings` column with default values
- All existing tenants get default settings automatically
### Phase 2: Backend - Notification Service ✅
1. **Tenant Service Client** ([shared/clients/tenant_client.py](shared/clients/tenant_client.py))
- Added `get_notification_settings(tenant_id)` method
- Fetches notification settings via HTTP from Tenant Service
2. **WhatsApp Business Service** ([services/notification/app/services/whatsapp_business_service.py](services/notification/app/services/whatsapp_business_service.py))
- Modified to accept `tenant_client` parameter
- Added `_get_whatsapp_credentials(tenant_id)` method for credential resolution
- Falls back to global config if tenant credentials not available
- Logs which credentials are being used
3. **WhatsApp Service Wrapper** ([services/notification/app/services/whatsapp_service.py](services/notification/app/services/whatsapp_service.py))
- Updated to accept and pass `tenant_client` parameter
4. **Service Initialization** ([services/notification/app/main.py](services/notification/app/main.py))
- Initialize `TenantServiceClient` on startup
- Pass `tenant_client` to `WhatsAppService`
### Phase 3: Frontend - TypeScript Types ✅
1. **Settings Types** ([frontend/src/api/types/settings.ts](frontend/src/api/types/settings.ts))
- Created `NotificationSettings` interface
- Added to `TenantSettings` interface
- Added to `TenantSettingsUpdate` interface
- Added 'notification' to `SettingsCategory` type
### Phase 4: Frontend - Component ✅
1. **Notification Settings Card** ([frontend/src/pages/app/database/ajustes/cards/NotificationSettingsCard.tsx](frontend/src/pages/app/database/ajustes/cards/NotificationSettingsCard.tsx))
- Complete UI component with sections for:
- WhatsApp Configuration (credentials, API version, language)
- Email Configuration (from address, name, reply-to)
- Notification Preferences (PO, inventory, production, forecast alerts)
- Channel selection (email/WhatsApp) for each notification type
- Includes helpful setup instructions for WhatsApp Business
- Responsive design with proper styling
### Phase 5: Frontend - Translations ✅
1. **Spanish Translations**
- [frontend/src/locales/es/ajustes.json](frontend/src/locales/es/ajustes.json) - notification section added
- [frontend/src/locales/es/settings.json](frontend/src/locales/es/settings.json) - "notifications" tab added
2. **Basque Translations**
- [frontend/src/locales/eu/ajustes.json](frontend/src/locales/eu/ajustes.json) - notification section added
- [frontend/src/locales/eu/settings.json](frontend/src/locales/eu/settings.json) - "notifications" tab added
### Phase 6: Frontend - BakerySettingsPage Integration ✅
**File**: [frontend/src/pages/app/settings/bakery/BakerySettingsPage.tsx](frontend/src/pages/app/settings/bakery/BakerySettingsPage.tsx)
Applied 11 changes:
1. ✅ Added `Bell` icon to imports

8. ✅ Updated `handleDiscard` function
9. ✅ Added notifications tab trigger with Bell icon
10. ✅ Added notifications tab content with NotificationSettingsCard
11. ✅ Updated floating save button onClick condition
---
## How It Works
### Message Flow
1. **PO Event Triggered**: When a purchase order is approved, an event is published to RabbitMQ
2. **Event Consumed**: Notification service receives the event with `tenant_id` and supplier information
3. **Credentials Lookup**:
- `WhatsAppBusinessService._get_whatsapp_credentials(tenant_id)` is called
- Fetches notification settings from Tenant Service via HTTP
- Checks if `whatsapp_enabled` is `True`
- If tenant has WhatsApp enabled AND credentials configured → uses tenant credentials
- Otherwise → falls back to global environment variable credentials
4. **Message Sent**: Uses resolved credentials to send message via Meta WhatsApp API
5. **Logging**: Logs which credentials were used (tenant-specific or global)
### Configuration Levels
**Global (Fallback)**:
- Environment variables: `WHATSAPP_ACCESS_TOKEN`, `WHATSAPP_PHONE_NUMBER_ID`, etc.
- Used when tenant settings are not configured or WhatsApp is disabled
- Configured at deployment time
**Per-Tenant (Primary)**:
- Stored in `tenant_settings.notification_settings` JSON column
- Configured through UI in Bakery Settings → Notifications tab
- Each tenant can have their own WhatsApp Business credentials
- Takes precedence over global config when enabled and configured
---
## Next Steps
### 1. Run Database Migration
```bash
cd services/tenant
alembic upgrade head
```
This will add the `notification_settings` column to all existing tenant records with default values.
### 2. Restart Services
```bash
# Restart tenant service
kubectl rollout restart deployment/tenant-service -n bakery-ia
# Restart notification service
kubectl rollout restart deployment/notification-service -n bakery-ia
```
### 3. Access the UI
1. Navigate to **Settings → Bakery Settings**
2. Click the new **Notifications** tab
3. Enable WhatsApp notifications
4. Enter your WhatsApp Business credentials:
- Phone Number ID (from Meta Business Suite)
- Access Token (from Meta Business Suite)
- Business Account ID (from Meta Business Suite)
5. Configure notification preferences
6. Click **Save**
### 4. Test the Implementation
**Option A: Create a Test Purchase Order**
1. Go to Procurement → Purchase Orders
2. Create a new purchase order for a supplier with a phone number
3. Approve the purchase order
4. Check notification service logs to verify tenant credentials were used
**Option B: Check Logs**
```bash
# Watch notification service logs
kubectl logs -f deployment/notification-service -n bakery-ia | grep -i whatsapp
# You should see one of:
# "Using tenant-specific WhatsApp credentials" (tenant config)
# "Using global WhatsApp credentials" (fallback)
```
---

## Security Considerations
### Current Implementation
- ✅ Credentials stored in database (PostgreSQL JSONB)
- ✅ Access controlled by tenant isolation
- ✅ Only admin/owner roles can modify settings
- ✅ HTTPS required for API communication
- ✅ Password input type for access token field
### Future Enhancements (Optional)
- Implement field-level encryption for `whatsapp_access_token`
- Add audit logging for credential changes
- Implement credential rotation mechanism
- Add "Test Connection" button to verify credentials
- Rate limiting on settings updates
- Alert on failed message sends
---
## Backward Compatibility
**Fully Backward Compatible**
- Existing code continues to work without changes
- PO event consumer already passes `tenant_id` - no changes needed
- Falls back gracefully to global config if tenant settings not configured
- Migration adds default settings to existing tenants automatically
- No breaking changes to any existing APIs
---
## Build Status
**Frontend build completed successfully**
```bash
cd frontend && npm run build
```
**Result**: ✅ Built in 5.04s with no errors
The build warnings shown are pre-existing issues in the codebase and not related to the notification settings implementation.

### Frontend - BakerySettingsPage Integration
**File**: `frontend/src/pages/app/settings/bakery/BakerySettingsPage.tsx`
**Changes needed** (see `FRONTEND_CHANGES_NEEDED.md` for detailed instructions):
1. Add `Bell` icon to imports
2. Import `NotificationSettings` type
3. Import `NotificationSettingsCard` component
4. Add `notificationSettings` state variable
5. Load notification settings in useEffect
6. Add notifications tab trigger
7. Add notifications tab content
8. Update `handleSaveOperationalSettings` validation
9. Add `notification_settings` to mutation
10. Update `handleDiscard` function
11. Update floating save button condition
**Estimated time**: 15 minutes
## 🔄 How It Works
### Message Flow
1. **PO Event Triggered**: When a purchase order is approved, an event is published to RabbitMQ
2. **Event Consumed**: Notification service receives the event with `tenant_id` and supplier information
3. **Credentials Lookup**:
- `WhatsAppBusinessService._get_whatsapp_credentials(tenant_id)` is called
- Fetches notification settings from Tenant Service via HTTP
- Checks if `whatsapp_enabled` is `True`
- If tenant has WhatsApp enabled AND credentials configured → uses tenant credentials
- Otherwise → falls back to global environment variable credentials
4. **Message Sent**: Uses resolved credentials to send message via Meta WhatsApp API
5. **Logging**: Logs which credentials were used (tenant-specific or global)
### Configuration Levels
**Global (Fallback)**:
- Environment variables: `WHATSAPP_ACCESS_TOKEN`, `WHATSAPP_PHONE_NUMBER_ID`, etc.
- Used when tenant settings are not configured or WhatsApp is disabled
- Configured at deployment time
**Per-Tenant (Primary)**:
- Stored in `tenant_settings.notification_settings` JSON column
- Configured through UI in Bakery Settings → Notifications tab
- Each tenant can have their own WhatsApp Business credentials
- Takes precedence over global config when enabled and configured
### Backward Compatibility
✅ Existing code continues to work without changes
✅ PO event consumer already passes `tenant_id` - no changes needed
✅ Falls back gracefully to global config if tenant settings not configured
✅ Migration adds default settings to existing tenants automatically
## 📊 Testing Checklist
### Backend Testing
- [ ] Run tenant service migration: `cd services/tenant && alembic upgrade head`
- [ ] Verify `notification_settings` column exists in `tenant_settings` table
- [ ] Test API endpoint: `GET /api/v1/tenants/{tenant_id}/settings/notification`
- [ ] Test API endpoint: `PUT /api/v1/tenants/{tenant_id}/settings/notification`
- [ ] Verify notification service starts successfully with tenant_client
- [ ] Send test WhatsApp message with tenant credentials
- [ ] Send test WhatsApp message without tenant credentials (fallback)
- [ ] Check logs for "Using tenant-specific WhatsApp credentials" message
- [ ] Check logs for "Using global WhatsApp credentials" message
### Frontend Testing
- [ ] Apply BakerySettingsPage changes
- [ ] Navigate to Settings → Bakery Settings
- [ ] Verify "Notifications" tab appears
- [ ] Click Notifications tab
- [ ] Verify NotificationSettingsCard renders correctly
- [ ] Toggle "Enable WhatsApp" checkbox
- [ ] Verify credential fields appear/disappear
- [ ] Fill in WhatsApp credentials
- [ ] Verify helper text appears correctly
- [ ] Verify setup instructions appear
- [ ] Toggle notification preferences
- [ ] Verify channel checkboxes (Email/WhatsApp)
- [ ] WhatsApp channel checkbox should be disabled when WhatsApp not enabled
- [ ] Click Save button
- [ ] Verify success toast appears
- [ ] Refresh page and verify settings persist
- [ ] Test in both Spanish and Basque languages
### Integration Testing
- [ ] Configure tenant WhatsApp credentials via UI
- [ ] Create a purchase order for a supplier with phone number
- [ ] Approve the purchase order
- [ ] Verify WhatsApp message is sent using tenant credentials
- [ ] Check logs confirm tenant credentials were used
- [ ] Disable tenant WhatsApp in UI
- [ ] Approve another purchase order
- [ ] Verify message uses global credentials (fallback)
- [ ] Re-enable tenant WhatsApp
- [ ] Remove credentials (leave fields empty)
- [ ] Verify fallback to global credentials
## 🔒 Security Considerations
### Current Implementation
- ✅ Credentials stored in database (PostgreSQL JSONB)
- ✅ Access controlled by tenant isolation
- ✅ Only admin/owner roles can modify settings
- ✅ HTTPS required for API communication
- ✅ Password input type for access token field
### Future Enhancements (Recommended)
- [ ] Implement field-level encryption for `whatsapp_access_token`
- [ ] Add audit logging for credential changes
- [ ] Implement credential rotation mechanism
- [ ] Add "Test Connection" button to verify credentials
- [ ] Rate limiting on settings updates
- [ ] Alert on failed message sends

-`services/notification/WHATSAPP_QUICK_REFERENCE.md` - Quick reference
-`services/notification/MULTI_TENANT_WHATSAPP_IMPLEMENTATION.md` - Implementation details
### Documentation Updates Needed
- [ ] Update `WHATSAPP_SETUP_GUIDE.md` with per-tenant configuration instructions
- [ ] Add screenshots of UI settings page
- [ ] Document fallback behavior
- [ ] Add troubleshooting section for tenant-specific credentials
- [ ] Update API documentation with new tenant settings endpoint
## 🚀 Deployment Steps
### 1. Backend Deployment
```bash
# 1. Deploy tenant service changes
cd services/tenant
alembic upgrade head
kubectl apply -f kubernetes/tenant-deployment.yaml
# 2. Deploy notification service changes
cd services/notification
kubectl apply -f kubernetes/notification-deployment.yaml
# 3. Verify services are running
kubectl get pods -n bakery-ia
kubectl logs -f deployment/tenant-service -n bakery-ia
kubectl logs -f deployment/notification-service -n bakery-ia
```
### 2. Frontend Deployment
