Project description

django-whatsapp-api-wrapper

Importante: Esta biblioteca está em desenvolvimento ativo e ainda não possui cobertura de testes automatizados. As APIs podem mudar entre versões menores. Utilize com cautela em produção, valide os fluxos críticos e, se possível, contribua com issues/PRs.

Um wrapper simples para enviar mensagens via WhatsApp Cloud API e expor um endpoint de webhook, pronto para integrar em qualquer projeto Django.

Instalação

python -m pip install django-whatsapp-api-wrapper

Configuração (Django)

Adicione o app em INSTALLED_APPS:

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

Inclua as URLs no urls.py principal:

from django.urls import path, include

urlpatterns = [
    # ...
    path("whatsapp-api-wrapper/", include("django_whatsapp_api_wrapper.urls")),
]

Defina as variáveis de ambiente (ou no seu .env):

WHATSAPP_CLOUD_API_TOKEN=
WHATSAPP_CLOUD_API_PACKAGE_VERSION=0.1.1
WHATSAPP_CLOUD_API_VERSION=v23.0
WHATSAPP_CLOUD_API_PHONE_NUMBER_ID=
WHATSAPP_CLOUD_API_WABA_ID=
WHATSAPP_CLOUD_API_VERIFY_TOKEN=

Configure a autenticação para as rotas de templates (opcional, mas recomendado):

# settings.py

# Opção 1: Usar Token Authentication do DRF (padrão)
WHATSAPP_API_AUTHENTICATION_CLASSES = [
    'rest_framework.authentication.TokenAuthentication',
]

# Opção 2: Usar JWT (se você já tem configurado)
WHATSAPP_API_AUTHENTICATION_CLASSES = [
    'rest_framework_simplejwt.authentication.JWTAuthentication',
]

# Opção 3: Usar API Key simples
WHATSAPP_API_AUTHENTICATION_CLASSES = [
    'django_whatsapp_api_wrapper.authentication.APIKeyAuthentication',
]
WHATSAPP_API_KEY = "sua_api_key_secreta_aqui"

# Permissões (padrão: IsAuthenticated)
WHATSAPP_API_PERMISSION_CLASSES = [
    'rest_framework.permissions.IsAuthenticated',
]

Importante: Se não configurar a autenticação, as rotas de templates usarão TokenAuthentication por padrão. As rotas de mensagens herdam a mesma configuração.

O endpoint de webhook ficará disponível em:

GET/POST: /whatsapp-api-wrapper/webhook/
Verificação (GET): /whatsapp-api-wrapper/webhook/?hub.mode=subscribe&hub.verify_token=<TOKEN>&hub.challenge=123

Extensibilidade do Webhook

Você pode customizar o processamento do webhook no projeto hospedeiro de duas formas:

Via setting com handler plugável:

# settings.py
WHATSAPP_WEBHOOK_HANDLER = "meuapp.whatsapp.handle_webhook"

# meuapp/whatsapp.py
from django.http import JsonResponse

def handle_webhook(request, payload):
    # sua lógica aqui (salvar eventos, acionar tasks, etc)
    return JsonResponse({"ok": True})

Via signal webhook_event_received:

from django.dispatch import receiver
from django_whatsapp_api_wrapper.signals import webhook_event_received

@receiver(webhook_event_received)
def on_whatsapp_event(sender, payload, request, **kwargs):
    # sua lógica aqui
    pass

Mensagens

Envio e recebimento de mensagens via Cloud API.

Envio (Python)

from django_whatsapp_api_wrapper import WhatsApp
from django_whatsapp_api_wrapper.messages import types as WATypes

wp = WhatsApp()

# Texto (construa o objeto e passe o objeto diretamente)
text = WATypes.Text(body="olá do wrapper", preview_url=False)
m_text = wp.build_message(to="551199999999", type="text", data=text)
m_text.send()

# Template
tpl = WATypes.Template(name="opa", language={"code": "pt_BR"}, components=[])
m_tpl = wp.build_message(to="551199999999", type="template", data=tpl)
m_tpl.send()

# Sticker (exemplo com media ID)
stk = WATypes.Sticker(id="MEDIA_ID")
m_stk = wp.build_message(to="551199999999", type="sticker", data=stk)
m_stk.send()

# Imagem por URL
img = WATypes.Image(link="https://exemplo.com/foto.jpg", caption="Legenda")
m_img = wp.build_message(to="551199999999", type="image", data=img)
m_img.send()

Webhook

Recebe eventos (mensagens/atualizações de status) em GET/POST /whatsapp-api-wrapper/webhook/.
Verificação (GET): /whatsapp-api-wrapper/webhook/?hub.mode=subscribe&hub.verify_token=<TOKEN>&hub.challenge=123.
Personalize via setting WHATSAPP_WEBHOOK_HANDLER ou escute o signal webhook_event_received (veja seção Extensibilidade do Webhook acima).

Endpoints HTTP de Mensagens (DRF)

Prefixo base: /whatsapp-api-wrapper/messages/

⚠️ Importante: Todos os endpoints de mensagens requerem autenticação (veja seção Autenticação acima).

Enviar mensagem (genérico)

POST /whatsapp-api-wrapper/messages/send/

  ]}
} }

Autenticação

Proteção das Rotas de API

Por padrão, todas as rotas de templates (/templates/) e mensagens (/messages/) são protegidas e requerem autenticação. O webhook permanece público (necessário para o WhatsApp).

Opções de Autenticação

1. Token Authentication (Padrão)

# settings.py
WHATSAPP_API_AUTHENTICATION_CLASSES = [
    'rest_framework.authentication.TokenAuthentication',
]

Uso:

curl -H "Authorization: Token seu_token_aqui" \
     "$BASE/whatsapp-api-wrapper/templates/"

2. JWT Authentication

# settings.py
WHATSAPP_API_AUTHENTICATION_CLASSES = [
    'rest_framework_simplejwt.authentication.JWTAuthentication',
]

Uso:

curl -H "Authorization: Bearer seu_jwt_token" \
     "$BASE/whatsapp-api-wrapper/templates/"

3. API Key Authentication

# settings.py
WHATSAPP_API_AUTHENTICATION_CLASSES = [
    'django_whatsapp_api_wrapper.authentication.APIKeyAuthentication',
]
WHATSAPP_API_KEY = "sua_api_key_secreta"

Uso:

curl -H "X-WhatsApp-API-Key: sua_api_key_secreta" \
     "$BASE/whatsapp-api-wrapper/templates/"

4. Múltiplas Autenticações

# settings.py
WHATSAPP_API_AUTHENTICATION_CLASSES = [
    'rest_framework.authentication.TokenAuthentication',
    'django_whatsapp_api_wrapper.authentication.APIKeyAuthentication',
]

Permissões Customizadas

# settings.py
WHATSAPP_API_PERMISSION_CLASSES = [
    'rest_framework.permissions.IsAuthenticated',
    # ou 'rest_framework.permissions.IsAdminUser',
    # ou 'myapp.permissions.CustomPermission',
]

Templates

Endpoints REST (DRF) para gerenciar Message Templates do WhatsApp (proxy para Graph API). Todos os endpoints abaixo partem do prefixo que você incluir no projeto, por exemplo: .../whatsapp-api-wrapper/.

⚠️ Importante: Todos os endpoints de templates requerem autenticação (veja seção Autenticação acima).

Requisitos de ambiente: WHATSAPP_CLOUD_API_TOKEN, WHATSAPP_CLOUD_API_VERSION, WHATSAPP_CLOUD_API_WABA_ID.

Aqui a documentação OFICIAL:

https://www.postman.com/meta/whatsapp-business-platform/folder/2ksdd2s/whatsapp-cloud-api

Listar e criar

GET GET /templates/?limit=&after=&before=
POST POST /templates/ com payload conforme a Graph API.

Exemplo de criação:

curl -X POST \
  "$BASE/whatsapp-api-wrapper/templates/" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "authentication_code_copy_code_button",
    "language": "en_US",
    "category": "AUTHENTICATION",
    "components": [
      {"type": "BODY", "add_security_recommendation": true},
      {"type": "FOOTER", "code_expiration_minutes": 10},
      {"type": "BUTTONS", "buttons": [{"type": "OTP", "otp_type": "COPY_CODE", "text": "Copy Code"}]}
    ]
  }'

Buscar por ID e editar

GET GET /templates/<template_id>/
POST POST /templates/<template_id>/ para editar (mesmo formato do corpo de criação).

Buscar e excluir por nome

GET GET /templates/by-name/?name=<TEMPLATE_NAME>
DELETE DELETE /templates/by-name/?name=<TEMPLATE_NAME>

Excluir por ID (hsm_id) e nome

DELETE DELETE /templates/delete-by-id/?hsm_id=<HSM_ID>&name=<NAME>

Obter namespace

GET GET /templates/namespace/

Notas:

Os payloads aceitos seguem a documentação oficial de Message Templates da Meta (Graph API). Este wrapper só valida campos básicos e encaminha a requisição.
As respostas retornadas são as mesmas da Graph API (status code e corpo JSON), para facilitar troubleshooting.
