Delete Blockchain Event Subscription

Through this endpoint the customer can delete blockchain event subscriptions they have by attributes referenceId and network.

Currently Crypto APIs 2.0 offers certain Blockchain event endpoints which allow the user to subscribe for one/a few/all and receive callback notifications when the specific event occurs.

To have an operational callback subscription, you need to first verify a domain for the Callback URL. Please see more information on Callbacks here.

Crypto APIs will notify the user only when the event occurs. There are cases when the specific event doesn't happen at all, or takes a long time to do so. A callback notification will not be sent if the event does not or cannot occur, or will take long time to occur.
