# WhatsApp Integration - Implementation Complete ✅
|
|
|
|
## Overview
|
|
Full WhatsApp Cloud API integration for wedding invitation templates has been successfully implemented and tested.
|
|
|
|
## What Was Implemented
|
|
|
|
### Backend (FastAPI + Python)
|
|
✅ **WhatsApp Service Module** (`whatsapp.py`)
|
|
- `send_wedding_invitation()` - Specialized method for wedding template messages
|
|
- E.164 phone normalization (e.g., 05XXXXXXXX → +9725XXXXXXXX)
|
|
- Full support for 7 template variables
|
|
|
|
✅ **Database Schema** (`models.py`)
|
|
- 5 new columns added to events table:
|
|
- `partner1_name` (bride/groom name 1)
|
|
- `partner2_name` (bride/groom name 2)
|
|
- `venue` (wedding venue)
|
|
- `event_time` (HH:mm format)
|
|
- `guest_link` (RSVP link)
|
|
|
|
✅ **API Endpoints** (`main.py`)
|
|
- `POST /events/{event_id}/guests/{guest_id}/whatsapp/invite` - Send to single guest
|
|
- `POST /events/{event_id}/whatsapp/invite` - Bulk send to multiple guests
|
|
- 0.5s rate limiting between sends
|
|
- Detailed success/failure reporting
|
|
|
|
✅ **Data Validation** (`crud.py`)
|
|
- CRUD functions for WhatsApp data queries
|
|
- Guest filtering and batch operations
|
|
- Event data retrieval for template variables
|
|
|
|
### Frontend (React + Vite)
|
|
✅ **WhatsAppInviteModal Component** (230 lines)
|
|
- Guest selection preview
|
|
- Event details form (all 7 template inputs)
|
|
- Live message preview
|
|
- Results screen with per-guest status
|
|
- Full Hebrew text with RTL support
|
|
- Dark/light theme compatibility
|
|
|
|
✅ **GuestList Integration**
|
|
- Checkbox selection for multiple guests
|
|
- "💬 שלח בוואטסאפ" button (appears when guests selected)
|
|
- Modal launch with pre-filled event data
|
|
- Results feedback
|
|
|
|
✅ **API Integration** (`api.js`)
|
|
- `sendWhatsAppInvitationToGuests()` - bulk endpoint
|
|
- `sendWhatsAppInvitationToGuest()` - single endpoint
|
|
- Error handling and status tracking
|
|
|
|
### Template Variable Mapping
|
|
Your approved Meta template automatically fills:
|
|
```
|
|
{{1}} = Guest first name (or "חבר" if empty)
|
|
{{2}} = Partner 1 name (user fills)
|
|
{{3}} = Partner 2 name (user fills)
|
|
{{4}} = Venue (user fills)
|
|
{{5}} = Event date → DD/MM format (auto)
|
|
{{6}} = Event time → HH:mm (user fills)
|
|
{{7}} = Guest RSVP link (user fills)
|
|
```
|
|
|

## Phone Number Formatting
|
|
|
|
The system auto-converts various formats to E.164 international standard:
|
|
|
|
| Input | Output |
|
|
|-------|--------|
|
|
| 05XXXXXXXX | +9725XXXXXXXX |
|
|
| +9725XXXXXXXX | +9725XXXXXXXX (unchanged) |
|
|
| +1-555-1234567 | +15551234567 |
|
|
|
|
---
|
|
|
|
## Error Handling
|
|
|
|
- ❌ No valid phone? Shows in results as "failed"
|
|
- ❌ Template not approved? API returns clear error
|
|
- ❌ Missing event details? Modal validation prevents send
|
|
- ❌ One guest fails? Others still sent (resilient batch processing)
|
