Webhooks

Overview & setup

Webhooks tell your server about invoice lifecycle changes in real time, so you don't have to poll.

How they work

When an invoice is created, paid, expires, or is canceled, we send a signed JSON POST to each active endpoint subscribed to that event. Your server verifies the signature and updates the order.

Setting up an endpoint

Configure endpoints in the dashboard. Open your store, go to its Developers tab, then Webhooks:

  1. Add one or more HTTPS endpoint URLs.
  2. Subscribe each endpoint to the events it needs.
  3. Copy the signing secret shown once at creation. You'll use it to verify signatures.
