# API de Webhooks

Los webhooks permiten recibir callbacks HTTP cuando ocurren eventos en Synapse.
Perfectos para disparar automatización externa, enviar notificaciones o
sincronizar con otros sistemas.

## Endpoints

### POST /webhooks

Registra un nuevo webhook.

```bash
curl -X POST https://synapse.schaefer.zone/webhooks \
  -H "Authorization: Bearer YOUR_MIND_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://my-app.com/webhook",
    "events": "memory.*",
    "secret": "my-hmac-secret-min-8-chars"
  }'
```

Respuesta:

```json
{
  "id": "wh_001",
  "url": "https://my-app.com/webhook",
  "events": ["memory.*"],
  "enabled": true,
  "created_at": "2026-06-27T..."
}
```

### GET /webhooks

Lista todos los webhooks del mind actual.

```bash
curl -H "Authorization: Bearer YOUR_MIND_KEY" \
     https://synapse.schaefer.zone/webhooks
```

### GET /webhooks/:id

Obtiene un webhook individual.

```bash
curl -H "Authorization: Bearer YOUR_MIND_KEY" \
     https://synapse.schaefer.zone/webhooks/wh_001
```

### PUT /webhooks/:id

Actualiza un webhook (URL, eventos, secreto o flag enabled).

```bash
curl -X PUT https://synapse.schaefer.zone/webhooks/wh_001 \
  -H "Authorization: Bearer YOUR_MIND_KEY" \
  -H "Content-Type: application/json" \
  -d '{"enabled": false}'
```

### DELETE /webhooks/:id

Elimina un webhook.

```bash
curl -X DELETE -H "Authorization: Bearer YOUR_MIND_KEY" \
     https://synapse.schaefer.zone/webhooks/wh_001
```

## Tipos de evento

| Patrón | Se dispara cuando |
|---------|------------|
| `memory.*` | Cualquier evento de memoria |
| `memory.store` | Nueva memoria almacenada |
| `memory.update` | Memoria actualizada |
| `memory.delete` | Memoria eliminada |
| `chat.*` | Cualquier evento de chat |
| `chat.message_received` | Nuevo mensaje del humano |
| `task.*` | Cualquier evento de tarea |
| `task.created` | Nueva tarea creada |
| `task.completed` | Tarea marcada como completada |
| `*` | Todos los eventos |

## Payload del webhook

Cuando se dispara un evento, Synapse hace POST a su URL:

```json
{
  "event": "memory.store",
  "timestamp": "2026-06-27T...",
  "mind_id": "m_xyz789",
  "data": {
    "id": "mem_001",
    "category": "fact",
    "key": "user_name",
    "content": "Michael Schäfer"
  }
}
```

## Verificación de firma

Si establece un `secret`, Synapse firma cada payload con HMAC-SHA256:

```
X-Synapse-Signature: sha256=<hex-hmac>
```

Verifíquelo en su handler:

```python
import hmac, hashlib

def verify_signature(payload_body: bytes, signature: str, secret: str) -> bool:
    expected = hmac.new(
        secret.encode(),
        payload_body,
        hashlib.sha256
    ).hexdigest()
    return hmac.compare_digest(f"sha256={expected}", signature)
```

## Patrón: sincronización en tiempo real

```python
# Your webhook handler
@app.post("/webhook")
async def handle_webhook(request):
    body = await request.body()
    signature = request.headers.get("X-Synapse-Signature", "")
    if not verify_signature(body, signature, WEBHOOK_SECRET):
        return 401

    event = json.loads(body)
    if event["event"] == "memory.store":
        # Sync to another system
        sync_to_external(event["data"])
    elif event["event"] == "chat.message_received":
        # Trigger agent wake-up
        notify_agent(event["data"])
```
