Public webhooks for subscription events
Subscribe to Subi events with merchant-configurable webhooks — signing secrets, multiple endpoints per topic, delivery logs, a test feature, and retries.
Subi now sends webhooks, so your systems can react to subscription events the moment they happen — no polling, no waiting. When something changes on a subscription, Subi posts a payload to the URL you register, so you can trigger fulfillment, update a CRM, fire an internal alert, or kick off any workflow of your own.
Configure your endpoints
Manage everything from the new Webhooks settings page:
- Register endpoints — add, edit, and remove the URLs Subi should call, and pick which event topics each one subscribes to.
- Multiple endpoints per topic — point the same event at more than one destination, so different systems can each receive it.
- Signing secret — every delivery is signed, and Subi generates a secret you use to verify each payload genuinely came from us before you trust it.
See what's being delivered
A delivery logs section shows recent deliveries with status badges, and each registered endpoint surfaces its last delivery status at a glance — so you can confirm events are landing and spot a misbehaving endpoint quickly. Use the built-in test feature to send a sample payload to any endpoint and check your integration end to end before you rely on it.
Built to be reliable
If a delivery fails, Subi retries it automatically with exponential backoff before giving up, so a brief outage on your side doesn't mean a lost event. A dedicated documentation page lists the available topics, the payload format, and how to verify the signature, so your developers have what they need to build against it.
