Webhooks send you signed events; the event log catches anything an endpoint missed. Add your endpoint's HTTPS URL, a description, and the events it should receive. Copy the signing secret now: it's shown once. Every delivery is signed with it, using HMAC-SHA256. A new endpoint starts disabled. Send a test event; when it succeeds, the endpoint is enabled. A failed delivery is retried up to ten times over 24 hours, and the event log keeps 30 days of events. Open an event to see its payload, then redeliver it to each enabled endpoint subscribed to its type.

How to start

Three steps from here

  1. Get a Testnet API key

    Sign up once and copy the key that is shown to you.

  2. Call the transfer API

    Create a mint from a wire and watch it settle on the ledger.

  3. Receive signed webhooks

    Point an endpoint at your server and verify the HMAC signature.
