Callback use case

Check a typical callback use case:

  1. Process — provide us a callback URL.
  2. API — create an order with the /orders or /sell/orders method.
  3. Process — get the transaction statuse update with the fields orderId, externalOrderId, and status from the /orders or /sell/orders response. Learn more details about the Transaction event payload section.
  4. API — send webhooks every time status updates. Learn more details about supported transaction statuses.

Also, we recommend you use signatures for requests to ensure that Changelly provides the transaction information, not a third party. More details with recommended best practices in the Webhooks signature section.
