Este guia cobre padrões comuns de automação.\n\n## Padrões comuns\n\n### Padrão 1: notificar em memória crítica\n\nEnvie uma mensagem Slack quando uma memória crítica é armazenada:\n\n```python\n# Webhook handler (your server)\n@app.post(\"/webhook\")\nasync def handle(request):\n    payload = await request.json()\n    \n    # Verify signature\n    if not verify_signature(payload, request.headers):\n        return 401\n    \n    if payload[\"event\"] == \"memory.store\":\n        memory = payload[\"data\"]\n        if memory.get(\"priority\") == \"critical\":\n            # Send Slack notification\n            await slack.post(\n                f\"🚨 Critical memory stored: {memory['key']}\\n{memory['content'][:200]}\"\n            )\n    \n    return 200\n```\n\nRegistre o webhook:\n\n```bash\ncurl -X POST https://synapse.schaefer.zone/webhooks \\\n  -H \"Authorization: Bearer YOUR_MIND_KEY\" \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\n    \"url\": \"https://my-app.com/webhook\",\n    \"events\": \"memory.store\",\n    \"secret\": \"my-hmac-secret\"\n  }'\n```\n\n### Padrão 2: sincronizar com sistema externo\n\nSincronize memórias com Notion, Obsidian ou qualquer KB externo:\n\n```python\n@app.post(\"/webhook\")\nasync def sync_to_notion(request):\n    payload = await request.json()\n    \n    if payload[\"event\"] == \"memory.store\":\n        memory = payload[\"data\"]\n        # Create Notion page\n        await notion.create_page(\n            title=memory[\"key\"],\n            content=memory[\"content\"],\n            tags=memory.get(\"tags\", [])\n        )\n    \n    elif payload[\"event\"] == \"memory.delete\":\n        # Delete from Notion\n        await notion.delete_page(memory_id=payload[\"data\"][\"id\"])\n    \n    return 200\n```\n\n### Padrão 3: disparar CI/CD\n\nDispare um deploy quando uma memória \"release\" é armazenada:\n\n```python\n@app.post(\"/webhook\")\nasync def trigger_deploy(request):\n    payload = await request.json()\n    \n    if payload[\"event\"] == \"memory.store\":\n        memory = payload[\"data\"]\n        if memory.get(\"key\", \"\").startswith(\"release_\"):\n            # Trigger GitLab pipeline\n            await gitlab.trigger_pipeline(\n                project=\"synapse\",\n                ref=\"main\",\n                variables={\"RELEASE_MEMORY_ID\": memory[\"id\"]}\n            )\n    \n    return 200\n```\n\n### Padrão 4: acordar agente em mensagem humana\n\nDispare uma execução de agente LLM quando um humano envia uma mensagem de chat:\n\n```python\n@app.post(\"/webhook\")\nasync def wake_agent(request):\n    payload = await request.json()\n    \n    if payload[\"event\"] == \"chat.message_received\":\n        message = payload[\"data\"]\n        # Queue agent processing job\n        await job_queue.enqueue(\n            \"process_message\",\n            message_id=message[\"id\"],\n            content=message[\"content\"]\n        )\n    \n    return 200\n```\n\n### Padrão 5: agregar métricas\n\nRastreie crescimento de memória, atividade de chat, conclusão de tarefas:\n\n```python\n@app.post(\"/webhook\")\nasync def track_metrics(request):\n    payload = await request.json()\n    event = payload[\"event\"]\n    \n    metrics = {\n        \"memory.store\": \"memories_stored_total\",\n        \"memory.delete\": \"memories_deleted_total\",\n        \"chat.message_received\": \"messages_received_total\",\n        \"task.created\": \"tasks_created_total\",\n        \"task.completed\": \"tasks_completed_total\",\n    }\n    \n    if event in metrics:\n        await prometheus.increment(metrics[event])\n    \n    return 200\n```\n\n## Verificação de assinatura\n\nSempre verifique assinaturas de webhook para evitar spoofing:\n\n```python\nimport hmac\nimport hashlib\n\ndef verify_signature(payload_body: bytes, headers, secret: str) -> bool:\n    signature = headers.get(\"X-Synapse-Signature\", \"\")\n    if not signature.startswith(\"sha256=\"):\n        return False\n    \n    expected = hmac.new(\n        secret.encode(),\n        payload_body,\n        hashlib.sha256\n    ).hexdigest()\n    \n    return hmac.compare_digest(f\"sha256={expected}\", signature)\n```\n\n## Lógica de retry\n\nO Synapse refaz webhooks falhados com backoff exponencial. Seu handler deve:\n\n1. **Retornar 200 rapidamente** — não faça trabalho pesado sincronamente\n2. **Enfileirar trabalho** — use um sistema de jobs em background\n3. **Ser idempotente** — o mesmo evento pode ser entregue duas vezes\n\n```python\n@app.post(\"/webhook\")\nasync def handle(request):\n    payload = await request.json()\n    # Queue for async processing\n    await job_queue.enqueue(\"process_webhook\", payload)\n    # Return immediately\n    return 200\n```\n\n## Depurando webhooks\n\n### Verifique o histórico de entrega\n\nEntregas de webhook são registradas. Confira as entregas recentes do seu\nwebhook:\n\n```bash\n# Get webhook details including recent deliveries\ncurl -H \"Authorization: Bearer YOUR_MIND_KEY\" \\\n     https://synapse.schaefer.zone/webhooks/wh_001\n```\n\n### Teste o webhook manualmente\n\n```bash\n# Trigger a test event\ncurl -X POST https://synapse.schaefer.zone/webhooks/wh_001/test \\\n  -H \"Authorization: Bearer YOUR_MIND_KEY\"\n```\n\n### Problemas comuns\n\n| Problema | Correção |\n|----------|----------|\n| Respostas 4xx | Verifique se seu handler retorna 200 |\n| Respostas 5xx | Erro de servidor — confira os logs do seu app |\n| Timeout | Retorne 200 rápido, enfileire trabalho assíncrono |\n| Entregas duplicadas | Torne o handler idempotente |\n| Incompatibilidade de assinatura | Verifique se o secret está correto |\n\n## Melhores práticas\n\n> [!TIP]\n> - **Sempre verifique assinaturas** — nunca pule isso\n> - **Retorne 200 rápido** — não bloqueie o Synapse\n> - **Seja idempotente** — trate entregas duplicadas\n> - **Use eventos específicos** — `memory.store` em vez de `*`\n> - **Monitore falhas de entrega** — configure alertas\n\n## Próximos passos\n\n- [API de Webhooks](/docs/api/webhooks)\n- [Cron & Agendador](/docs/api/cron)\n- [Agente LLM persistente](/docs/guides/persistent-llm-agent)\n","content_html":"<h1>Automação com webhooks</h1>\n<p>Webhooks permitem disparar sistemas externos quando eventos do Synapse\nocorrem.
