    • Direct API {refund}

    {refund} API function allows you to refund an approved deposit transaction.
    The refund is processed as a new transaction sent to the same PSP used for the original deposit, returning the amount back to the customer's account.

    {danger.fa-exclamation} IMPORTANT 1: The original referenced transaction (see the reference_id request parameter) must be a deposit with approved status.

    {danger.fa-exclamation} IMPORTANT 2: Ensure that the PSP supports the refund transaction type. If the refund amount differs from the original deposit amount, confirm that the PSP supports partial refunds.

    {danger.fa-exclamation} IMPORTANT 3: Whether issuing a refund via Atlas or Direct API, the refund transaction currency must match the processing currency of the original deposit being refunded.

    {danger.fa-exclamation} IMPORTANT 4: Direct API's refund functionality does not require PCI certification. Since no card data is transmitted through this resource, there are no associated PCI compliance requirements.
