A POST request sent to the user’s callback URL to notify about a new transaction (transfers, deposits or payouts) in a blockchain. Callbacks can be used to make changes in the user’s system and notify user’s payers. By default, the callback is sent after the transaction is confirmed. The number of confirmations is determined in the confirmation_blocks field in the currency settings. It is also possible to receive additional callbacks by specifying a required number in the confirmation_needed field when creating a deposit or creating an invoice. Upon receiving a required number of confirmations related to a new transaction, a callback is sent to the user’s server if the transaction request body includes a valid callback URL.
