📦 Installation

# Using uv (Recommended)
uv add django-meta-whatsapp

# Using pip
pip install django-meta-whatsapp

⚙️ Configuration

1. Add to INSTALLED_APPS:

INSTALLED_APPS = [
    # ...
    "django_meta_whatsapp",
]

2. Mount URLs in urls.py:

from django.urls import path, include

urlpatterns = [
    # ...
    path("whatsapp/", include("django_meta_whatsapp.urls", namespace="django_meta_whatsapp")),
]

3. Add WHATSAPP settings to settings.py:

WHATSAPP = {
    # ── Required ──────────────────────────────────────────
    "API_TOKEN": "EAA...",
    "PHONE_NUMBER_ID": "1234567890",
    "WEBHOOK_VERIFY_TOKEN": "your_secure_random_string",

    # ── UI Customization (optional) ───────────────────────
    "DASHBOARD_NAME": "My Business CRM",
    "DASHBOARD_LOGO": "https://yourwebsite.com/logo.png",

    # ── Audience Providers (optional) ─────────────────────
    # Map your own model querysets as named campaign audiences
    "PHONE_FIELD": "phone",       # field on your model with the phone number
    "NAME_FIELD": "name",         # field on your model with the display name
    "AUDIENCES": {
        "All Users":     "myapp.audiences.all_users",
        "VIP Customers": "myapp.audiences.vip_customers",
    },

    # ── Contact Filter Presets (optional) ─────────────────
    # Pre-defined filters shown as a dropdown in the Campaign form
    "CONTACT_FILTERS": {
        "VIP Customers":        '{"labels__name": "VIP"}',
        "Subscribed via Link":  '{"subscribed_via_signup__isnull": false}',
        "New This Month":       '{"created_at__gte": "2024-06-01"}',
    },

    # ── Security & Encryption (optional) ──────────────────
    # Derived from SECRET_KEY by default. Used to symmetrically encrypt access tokens in DB.
    "ENCRYPTION_KEY": "your_custom_secret_key_or_password",
}

4. Run migrations:

python manage.py migrate

5. Credential Encryption (Secure-by-Default): Database-stored access tokens (in the WhatsAppAccount model) are automatically encrypted using symmetric encryption (Fernet).

• Default Key: The encryption key is derived automatically from your Django project's SECRET_KEY.
• Custom Key: To use a separate key, define "ENCRYPTION_KEY" inside your WHATSAPP settings.
• Upgrades: If you have existing plain text tokens, the database fallback will read them cleanly. Saving the account again will seamlessly encrypt it.

🚀 Quickstart

1. Visit /whatsapp/ in your browser.
2. The UI will prompt you to add a WhatsApp Account if none exists.
3. Set your Meta App Webhook URL to https://yourdomain.com/whatsapp/webhook/.
4. Sync your templates from the Templates tab.
5. Start chatting from the Inbox!

🔗 Linking Your Django User Model

You can link WhatsAppContact to your existing User model without modifying the package. Three approaches are documented:

Option A — Profile Model (recommended):

from django_meta_whatsapp.models import WhatsAppContact

class UserWhatsAppProfile(models.Model):
    user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name="whatsapp_profile")
    contact = models.OneToOneField(WhatsAppContact, on_delete=models.SET_NULL, null=True, blank=True)

Option B — Query your User model directly as a campaign audience:

# myapp/audiences.py
from django.contrib.auth import get_user_model
User = get_user_model()

def all_users():
    return User.objects.filter(is_active=True, phone__isnull=False)

See the full documentation for signals-based auto-linking and more filter patterns.

🔑 REST API

All endpoints require an X-API-Key header (generated from the dashboard under Settings → API Keys).

# Send a text message
curl -X POST https://yourdomain.com/whatsapp/api/send-message/ \
  -H "X-API-Key: your-key" \
  -H "Content-Type: application/json" \
  -d '{"phone": "919876543210", "message": "Hello!"}'

# Send an approved template
curl -X POST https://yourdomain.com/whatsapp/api/send-template/ \
  -H "X-API-Key: your-key" \
  -H "Content-Type: application/json" \
  -d '{"phone": "919876543210", "template_name": "order_update", "language": "en", "body_params": ["Rahul", "ORD-999"]}'
