Webhook-automatisering

\n

Met webhooks kunt u externe systemen triggeren wanneer Synapse-gebeurtenissen vuren. Deze handleiding\nbehandelt veelvoorkomende automatiseringspatronen.

\n

Veelvoorkomende patronen

\n

Patroon 1: Melding bij kritieke herinnering

\n

Stuur een Slack-bericht wanneer een kritieke herinnering wordt opgeslagen:

\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

Registreer de webhook:

\n
curl -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  }'

Patroon 2: Synchroniseer naar extern systeem

\n

Synchroniseer herinneringen naar Notion, Obsidian of een externe KB:

\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

Patroon 3: Trigger CI/CD

\n

Trigger een deployment wanneer een "release"-herinnering wordt opgeslagen:

\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

Patroon 4: Word agent wakker bij menselijk bericht

\n

Trigger een LLM-agent-run wanneer een mens een chatbericht stuurt:

\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

Patroon 5: Geaggregeerde metrics

\n

Volg memory-groei, chat-activiteit, taakvoltooiing:

\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

Handtekeningverificatie

\n

Verifieer altijd webhook-handtekeningen om spoofing te voorkomen:

\n
import 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)

Retry-logica

\n

Synapse probeert mislukte webhooks opnieuw met exponentiële backoff. Uw handler moet:

\n
    \n
  1. Snel 200 retourneren — doe niet zwaar werk synchroon
    2. \n
  2. Werk in wachtrij plaatsen — gebruik een achtergrond-job-systeem
    3. \n
  3. Idempotent zijn — dezelfde gebeurtenis kan twee keer worden geleverd
    4. \n
\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

Webhooks debuggen

\n

Leveringsgeschiedenis controleren

\n

Webhook-leveringen worden gelogd. Controleer recente leveringen van uw webhook:

\n
# Get webhook details including recent deliveries\ncurl -H "Authorization: Bearer YOUR_MIND_KEY" \\\n     https://synapse.schaefer.zone/webhooks/wh_001

Test webhook handmatig

\n
# Trigger a test event\ncurl -X POST https://synapse.schaefer.zone/webhooks/wh_001/test \\\n  -H "Authorization: Bearer YOUR_MIND_KEY"
