Payment API {process} Refund
Payment Card Processing API lets you process the credit and debit card deposits and payouts over REST API.
{danger.fa-exclamation} IMPORTANT: Sometimes
transaction_id(PSP transaction identifier) is empty, this may happen in the cases when the PSP has rejected the processing attempt due to input validation or unavailability of the payment gateway.
