API de Webhooks

Webhooks permitem receber callbacks HTTP quando eventos acontecem no Synapse. Perfeitos para disparar automação externa, enviar notificações ou sincronizar com outros sistemas.

Endpoints

POST /webhooks

Registra um novo webhook.

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"
  }'

Resposta:

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

GET /webhooks

Lista todos os webhooks do mind atual.

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

GET /webhooks/:id

Obtém um único webhook.

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

PUT /webhooks/:id

Atualiza um webhook (URL, eventos, secret ou flag enabled).

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

Exclui um webhook.

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

Tipos de evento

Payload do webhook

Quando um evento dispara, o Synapse faz POST para sua URL:

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

Verificação de assinatura

Se você definir um secret, o Synapse assina cada payload com HMAC-SHA256:

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

Verifique no seu handler:

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)

Padrão: sincronização em tempo real

# 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"])
