New Confirmed Internal Transactions And Each Confirmation

POST

/blockchain-events/{blockchain}/{network}/subscriptions/address-internal-transactions-confirmed-each-confirmation

Through this endpoint customers can create callback subscriptions for a specific event. In this case the event is when there are new confirmed internal transactions. Includes also a response at each confirmation the transaction receives until the specified confirmations limit is reached. By creating this subscription the user will be notified by Crypto APIs 2.0 when that event occurs.

Being confirmed means that the transactions are verified by miners and added to the next block.

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.

Path Parameters

blockchain string Required

Represents the specific blockchain protocol name, e.g. Ethereum, Bitcoin, etc.
