Webhooks

Subscribe to Formuley events, choose a safe endpoint, verify signatures, and troubleshoot deliveries.

Overview

Webhooks let Formuley push outbound events to your application instead of forcing you to poll the API continuously.

Manage webhook endpoints from /developer/webhooks or through the REST API under /api/v1/webhooks.

What you can subscribe to

Current event types in code include:

  • formula.created
  • formula.updated
  • formula.deleted
  • ingredient.created
  • ingredient.updated
  • ingredient.deleted
  • ingredient.low_stock
  • batch.created
  • batch.updated
  • batch.completed
  • order.created
  • order.updated
  • compliance.check_completed

The webhook test route also sends a test.ping event when you trigger a test delivery.

Endpoint requirements

For real integrations, use a public HTTPS endpoint you control.

The delivery system rejects private, internal, and non-HTTPS destinations. The create and test flows both expect resolvable public HTTPS URLs.

Signature verification

Deliveries include these headers:

X-Formuley-Signature: sha256=...
X-Formuley-Event: formula.created
X-Formuley-Delivery: <delivery-id>

Verify the signature with your webhook secret and the raw request body before processing the payload.

Delivery behavior

The REST API includes:

  • /api/v1/webhooks to create and list endpoints
  • /api/v1/webhooks/[id] to read, update, or delete a webhook
  • /api/v1/webhooks/[id]/test to send a test event
  • /api/v1/webhooks/[id]/deliveries to inspect delivery history

Use the delivery history first when debugging failures.

Operational recommendations

  • Use one endpoint per environment.
  • Keep handlers idempotent.
  • Log payloads and response codes during initial setup.
  • Start with a narrow event set and expand once the integration is stable.

Troubleshooting

  • If the endpoint never receives test traffic, confirm the URL is public and reachable.
  • If signature verification fails, hash the raw request body rather than a parsed or re-serialized version.
  • If you see duplicate effects, store delivery or event identifiers and make processing idempotent.
