    Direct API {refund}

    {refund} API function lets you refund the approved deposit transaction. The refund will be a new transaction sent to the same PSP as the one used for the original deposit transaction in order to send the same amount back to customer's account.

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

    {danger.fa-exclamation} IMPORTANT #2: Please make sure that the PSP supports the refund transaction type. If the refund amount is different from the original deposit amount, you will also need to confirm that the PSP supports the partial refunds.

    {danger.fa-exclamation} IMPORTANT #3: Direct API does not support conversion, meaning that filter currency and processing currency must always match. It means the currency sent to Praxis within the Direct API sale, payout or refund call will be the same currency as we send to PSPs for processing.

    We are using Cryptocurrency Prices, Portfolio, Forum, Rankings for crypto currencies, and Open Exchange Rates for FIAT currencies. The rates information is updated every 15 minutes.
