Response

An associative array that contains the following keys:

Param name	Description	Type
`STATUS`	(Mandatory) The method execution status. Valid values for the Refund method are: `APPROVED`: The request is successfully processed and the payment gateway approved the transaction. `DECLINED`The request is successfully processed and the payment gateway declined the transaction. `FRAUD`: The request is successfully processed and the payment gateway declined the transaction due to a suspected fraud. `PENDING`: The request is successfully processed, but the transaction has the pending status in the payment gateway. The `NEXT_TRANSACTION_GAP` parameter may be used together with this status, so Billing can schedule the CheckStatus method call to verify whether the status is changed in the payment gateway. Refer to the `NEXT_TRANSACTION_GAP` parameter for details. `ERROR`: An error occurred while processing the request. The error reason can be sent in the `TEXT` parameter.	string
`TEXT`	(Optional) The array that contains the following parameters: `customer_message`: Contains text that will be displayed to a customer as a status message (String, optional). `vendor_message`: Contains text that will be displayed to a vendor (String, optional).	array
`TRANSACTION_DETAIL`	(Optional) The array that will be associated with the current transaction and will be represented back in unchanged form as the value of the `previous_transaction_data` parameter at the next call of transaction processing methods of the plugin. Note: Billing looks up the `trans_id` parameter that identifies a transaction on the gateway side to display it in the provider's UI. We highly recommend that you use this parameter.	array
`NEXT_TRANSACTION_GAP`	(Optional) The delay, in seconds, to dispatch the CheckStatus method call. This parameter may be used when the `STATUS` parameter is `PENDING`. When Billing receives this parameter, it will schedule the CheckStatus method call event to be dispatched in `NEXT_TRANSACTION_GAP` seconds. It may be useful when the payment gateway expects API consumers to actively check a transaction status.	integer

Example

The built-in Demo plugin implements the RefundCredit method. The example below shows how this plugin implements it:

Example

Copy

function Demo_RefundCredit( $params ) {
    if (!isset($params['transaction_amount'])) {
        throw new Exception('No transaction amount is set');
    }

    if (!isset($params['currency_iso']) ) {
        throw new Exception('No currency is set');
    }

    return array(
        STATUS => STATUS_APPROVED,
        TRANSACTION_DETAILS => array(
            'trans_id' => _Demo_FakeTransactionId()
        )
    );
}
