Webhooks

Webhooks expose functions as HTTP endpoints. When a request arrives at a webhook path, Sinas executes the linked function with the request data. Key properties:

Property	Description
`path`	URL path (e.g., `stripe/payment-webhook`)
`http_method`	GET, POST, PUT, DELETE, or PATCH
`function_namespace` / `function_name`	Target function
`requires_auth`	Whether the caller must provide a Bearer token
`default_values`	Default parameters merged with request data (request takes priority)

How input is extracted:

POST/PUT/PATCH with JSON body → body becomes the input
GET → query parameters become the input
Default values are merged underneath (request data overrides)

Example:

# Create a webhook
curl -X POST https://yourdomain.com/api/v1/webhooks \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "path": "stripe/payment",
    "function_namespace": "payments",
    "function_name": "process_webhook",
    "http_method": "POST",
    "requires_auth": false,
    "default_values": {"source": "stripe"}
  }'

# Trigger it
curl -X POST https://yourdomain.com/webhooks/stripe/payment \
  -H "Content-Type: application/json" \
  -d '{"event": "charge.succeeded", "amount": 1000}'

# Function receives: {"source": "stripe", "event": "charge.succeeded", "amount": 1000}

Endpoints:

POST   /api/v1/webhooks              # Create webhook
GET    /api/v1/webhooks              # List webhooks
GET    /api/v1/webhooks/{path}       # Get webhook
PATCH  /api/v1/webhooks/{path}       # Update webhook
DELETE /api/v1/webhooks/{path}       # Delete webhook
