Mined Transaction

Through this endpoint customers can create callback subscriptions for a specific event. In this case the event is when a specific transaction is mined. By creating this subscription the user will be notified by Crypto APIs 2.0 when that event occurs. The information is returned per specified transactionId.

A transaction is mined when it is included in a new block in the blockchain.

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.

Supports Callback Functionality Single Result - This endpoint returns only one single result. POST /blockchain-events/{blockchain}/{network}/subscriptions/transaction-mined

Path Parameters
