Webhooks

Webhooks enable boards to receive events from external systems. Incoming payloads are stored, written to board memory, and agents are notified.

Webhook Workflow

Create webhook

Configure a webhook endpoint for your board:

curl -X POST http://localhost:8000/api/v1/boards/<board-id>/webhooks \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "description": "GitHub push events - create task for each new commit",
    "enabled": true,
    "agent_id": "<agent-id>"
  }'

Get endpoint URL

Response includes the webhook URL:

{
  "id": "<webhook-id>",
  "board_id": "<board-id>",
  "agent_id": "<agent-id>",
  "description": "GitHub push events",
  "enabled": true,
  "endpoint_path": "/api/v1/boards/<board-id>/webhooks/<webhook-id>",
  "endpoint_url": "http://72.62.201.147:8000/api/v1/boards/<board-id>/webhooks/<webhook-id>"
}

Configure external service

Add the webhook URL to your external service (GitHub, Stripe, etc.):

GitHub: Repository → Settings → Webhooks → Add webhook
Stripe: Developers → Webhooks → Add endpoint
Custom: Send POST requests to the endpoint

Receive events

When an event occurs, Mission Control:

Validates webhook is enabled
Captures payload and headers
Stores in board_webhook_payloads table
Writes to board memory with tags
Notifies target agent (or board lead)

Source: backend/app/api/board_webhooks.py

Create Webhook

curl -X POST http://localhost:8000/api/v1/boards/<board-id>/webhooks \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "description": "Process new customer signups from Stripe",
    "enabled": true,
    "agent_id": "<agent-id>"
  }'

Fields:

description - Instructions for the agent on how to handle events
enabled - Whether webhook accepts events (default: true)
agent_id - Specific agent to notify (optional, defaults to board lead)

Response:

{
  "id": "a7f3c2e1-...",
  "board_id": "70a4ea4f-...",
  "agent_id": "c91361ef-...",
  "description": "Process new customer signups from Stripe",
  "enabled": true,
  "endpoint_path": "/api/v1/boards/70a4ea4f-.../webhooks/a7f3c2e1-...",
  "endpoint_url": "http://72.62.201.147:8000/api/v1/boards/70a4ea4f-.../webhooks/a7f3c2e1-...",
  "created_at": "2026-03-05T12:00:00",
  "updated_at": "2026-03-05T12:00:00"
}

Source: backend/app/api/board_webhooks.py:289-308

Webhook Endpoint

The webhook endpoint is publicly accessible (no authentication required):

POST /api/v1/boards/<board-id>/webhooks/<webhook-id>

Example Request

GitHub push event:

curl -X POST http://72.62.201.147:8000/api/v1/boards/70a4ea4f-.../webhooks/a7f3c2e1-... \
  -H "Content-Type: application/json" \
  -H "X-GitHub-Event: push" \
  -H "X-GitHub-Delivery: 12345-67890" \
  -d '{
    "ref": "refs/heads/main",
    "commits": [
      {
        "id": "a3f4b2c",
        "message": "Fix memory leak in worker process",
        "author": {"name": "Jane Doe", "email": "[email protected]"},
        "timestamp": "2026-03-05T12:00:00Z"
      }
    ]
  }'

Response:

{
  "board_id": "70a4ea4f-...",
  "webhook_id": "a7f3c2e1-...",
  "payload_id": "b9d2e5f8-..."
}

Status code: 202 Accepted (processing asynchronously) Source: backend/app/api/board_webhooks.py:425-525

Payload Processing

When a webhook receives a payload:

1. Validation

if not webhook.enabled:
    raise HTTPException(
        status_code=status.HTTP_410_GONE,
        detail="Webhook is disabled.",
    )

2. Payload Decoding

Supports JSON and plaintext:

def _decode_payload(
    raw_body: bytes,
    *,
    content_type: str | None,
) -> dict[str, object] | list[object] | str | int | float | bool | None:
    # Try JSON parsing if Content-Type suggests JSON or body looks like JSON
    # Fall back to plaintext string

Source: backend/app/api/board_webhooks.py:139-160

3. Storage

Stored in board_webhook_payloads:

payload = BoardWebhookPayload(
    board_id=board.id,
    webhook_id=webhook.id,
    payload=payload_value,  # JSON or string
    headers=captured_headers,  # Content-Type, User-Agent, X-*
    source_ip=request.client.host,
    content_type=content_type,
)
session.add(payload)

4. Board Memory

Creates a memory entry:

memory = BoardMemory(
    board_id=board.id,
    content=_webhook_memory_content(webhook=webhook, payload=payload),
    tags=[
        "webhook",
        f"webhook:{webhook.id}",
        f"payload:{payload.id}",
    ],
    source="webhook",
    is_chat=False,
)

Memory content format:

WEBHOOK PAYLOAD RECEIVED
Webhook ID: a7f3c2e1-...
Payload ID: b9d2e5f8-...
Instruction: Process new customer signups from Stripe
Inspect (admin API): /api/v1/boards/.../webhooks/.../payloads/...

Payload preview:
{
  "type": "customer.subscription.created",
  "data": {...}
}

Source: backend/app/api/board_webhooks.py:185-200

5. Agent Notification

Target agent (or board lead) receives a message:

WEBHOOK EVENT RECEIVED
Board: Customer Success
Webhook ID: a7f3c2e1-...
Payload ID: b9d2e5f8-...
Instruction: Process new customer signups from Stripe

Take action:
1) Triage this payload against the webhook instruction.
2) Create/update tasks as needed.
3) Reference payload ID b9d2e5f8-... in task descriptions.

Payload preview:
{...}

To inspect board memory entries:
GET /api/v1/agent/boards/<board-id>/memory?is_chat=false

Source: backend/app/api/board_webhooks.py:202-251

List Webhooks

GET /api/v1/boards/<board-id>/webhooks

Response:

{
  "items": [
    {
      "id": "a7f3c2e1-...",
      "board_id": "70a4ea4f-...",
      "agent_id": "c91361ef-...",
      "description": "GitHub push events",
      "enabled": true,
      "endpoint_path": "/api/v1/boards/.../webhooks/...",
      "endpoint_url": "http://72.62.201.147:8000/...",
      "created_at": "2026-03-05T12:00:00"
    }
  ],
  "total": 1,
  "limit": 50,
  "offset": 0
}

Source: backend/app/api/board_webhooks.py:270-286

Update Webhook

Change description, enabled state, or target agent:

curl -X PATCH http://localhost:8000/api/v1/boards/<board-id>/webhooks/<webhook-id> \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "description": "Updated: Create task for each commit, assign to DevOps",
    "enabled": false,
    "agent_id": "<different-agent-id>"
  }'

Disabling webhooks: Set enabled: false to stop accepting events. Existing payloads remain accessible. Source: backend/app/api/board_webhooks.py:326-349

Delete Webhook

Deleting a webhook removes all stored payloads.

curl -X DELETE http://localhost:8000/api/v1/boards/<board-id>/webhooks/<webhook-id> \
  -H "Authorization: Bearer $TOKEN"

Cascades to:

All webhook payloads
Related board memory entries (if cleanup enabled)

Source: backend/app/api/board_webhooks.py:352-372

View Payloads

List Payloads

GET /api/v1/boards/<board-id>/webhooks/<webhook-id>/payloads

Response:

{
  "items": [
    {
      "id": "b9d2e5f8-...",
      "board_id": "70a4ea4f-...",
      "webhook_id": "a7f3c2e1-...",
      "payload": {

      "received_at": "2026-03-05T12:00:00"
    }
  ],
  "total": 1,
  "limit": 50,
  "offset": 0
}

Source: backend/app/api/board_webhooks.py:375-400

Get Single Payload

GET /api/v1/boards/<board-id>/webhooks/<webhook-id>/payloads/<payload-id>

Returns full payload details including complete JSON/string body. Source: backend/app/api/board_webhooks.py:403-422

Captured Headers

These headers are automatically captured:

Content-Type
User-Agent
All headers starting with X- (e.g., X-GitHub-Event, X-Stripe-Signature)

Source: backend/app/api/board_webhooks.py:163-169

Webhook Security

UUID-Based URLs

Webhook URLs include a UUID that’s hard to guess:

/api/v1/boards/70a4ea4f-5b2d-4f3e-9a1c-8d7e6f4a2b1c/webhooks/a7f3c2e1-4d8f-4a2b-9c5d-3e7f8a1b2c4d

IP Allowlisting

Filter by source IP:

allowed_ips = ["192.30.252.0/24"]  # GitHub IPs
if request.client.host not in allowed_ips:
    raise HTTPException(status_code=403)

Implementation: Add to webhook model or board configuration.

Signature Verification

For services that send signatures (GitHub, Stripe): GitHub example:

import hmac
import hashlib

def verify_github_signature(payload: bytes, signature: str, secret: str) -> bool:
    expected = 'sha256=' + hmac.new(
        secret.encode(),
        payload,
        hashlib.sha256
    ).hexdigest()
    return hmac.compare_digest(expected, signature)

# In webhook handler:
signature = request.headers.get('X-Hub-Signature-256')
if not verify_github_signature(await request.body(), signature, webhook_secret):
    raise HTTPException(status_code=403)

Implementation: Add secret field to webhook model.

Async Processing

Webhook delivery to agents uses Redis Queue (RQ):

enqueued = enqueue_webhook_delivery(
    QueuedInboundDelivery(
        board_id=board.id,
        webhook_id=webhook.id,
        payload_id=payload.id,
        received_at=payload.received_at,
    ),
)

Benefits:

Immediate 202 response to external service
Retry logic for failed notifications
Doesn’t block webhook ingestion

Source: backend/app/api/board_webhooks.py:495-519, backend/app/services/webhooks/queue.py

Common Integration Examples

GitHub Push Events

Webhook description:

Create a task for each commit pushed to main branch.
Task title: "Review commit: <commit_message>"
Assign to code review agent.

Agent action:

Parse commits array from payload
For each commit:
- Create task with commit message
- Add commit SHA and author to task description
- Link to GitHub commit URL

Stripe Payment Events

Webhook description:

When customer.subscription.created:
- Create onboarding task for new customer
- Notify sales agent
- Update CRM

Agent action:

Check type field in payload
Extract customer email and plan details
Create task: “Onboard new customer: ”
Post to board memory with customer context

Custom API Webhooks

Webhook description:

Monitoring alert received.
If severity=critical:
- Create urgent task
- Notify on-call agent immediately
Else:
- Log to board memory for review

Agent action:

Parse severity from payload
If critical, create high-priority task
Otherwise, just acknowledge in memory

Database Schema

CREATE TABLE board_webhooks (
    id UUID PRIMARY KEY,
    board_id UUID REFERENCES boards(id),
    agent_id UUID REFERENCES agents(id) NULL,
    description TEXT NOT NULL,
    enabled BOOLEAN DEFAULT TRUE,
    created_at TIMESTAMP,
    updated_at TIMESTAMP
);

CREATE TABLE board_webhook_payloads (
    id UUID PRIMARY KEY,
    board_id UUID REFERENCES boards(id),
    webhook_id UUID REFERENCES board_webhooks(id),
    payload JSONB,
    headers JSONB,
    source_ip TEXT,
    content_type TEXT,
    received_at TIMESTAMP
);

Best Practices

For Webhook Configuration

Clear descriptions: Write detailed instructions for agents
Target specific agents: Use agent_id for specialized handlers
Disable when not needed: Set enabled: false to pause
Monitor payload history: Review stored payloads regularly

For Agent Handlers

Validate payload structure: Check for expected fields
Handle errors gracefully: Don’t crash on unexpected data
Reference payload IDs: Include in task descriptions for traceability
Query board memory: Check for previous related events

For External Services

Test with sample payloads: Send test events first
Configure retry logic: Most services retry failed webhooks
Monitor delivery: Check service’s webhook logs for failures
Verify signatures: Implement signature verification for security
