New confirmed coins transactions and each confirmation

Through this endpoint customers can create callback subscriptions for a specific event. In this case the event is when there are new incoming or outgoing confirmed transactions for coins from/to the customer's address with also a response at each confirmation the transaction has received 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. The information is returned per specified address.

Being confirmed means that the transactions are verified by miners and added to the next block. This endpoint refers to coins transactions only, not tokens.

For UTXO-based protocols like Bitcoin a transaction could have multiple inputs and outputs which means the address could in as both sender and recipient. Here is how we inform you on that.

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/address-coins-transactions-confirmed-each-confirmation

Path Parameters
