Create Subscriptions for

With Crypto APIs 2.0 and Blockchain Events you can set up subscriptions to receive a callback whenever a specific events occurs. Various endpoints are available for callback subscription. Callback subscription can be set from the Crypto APIs 2.0 Dashboard. They require a Callback URL where the actual callback will be received at.

Crypto APIs 2.0 Callbacks will be sent along with a retry logic if the first one is not accepted by the customer's end.

Note, that a Callback will be sent only when the event occurs. In some cases this may take a long time, in others it may never even happen. This is not up to Crypto APIs.

It is important to note that in order to set a valid and working Callback subscription, the domain for the Callback URL must be first verified.

To see more information on Callbacks and how they operate, please see our dedicated documentation.
