| Field Name | Description |
| --- | --- |
| REQUEST_REF_PO_ID | Reference Order ID is used when sending adjustment request against authorizations (i.e. Delayed Capture, Reversal and Credit requests). |
| REQUEST_REF_PO_LI_ID | Reference Line Item ID. Use this if multiple line items processing is needed. |
| CUST_ID | Customer ID created by the system after sending a successful authorization request. |
| REQUEST_REF_PO_ID_XTL | Request Reference XTL_ORDER_ID (Merchant’s Order ID). Used for sending CCSTATUS requests. |
| CREDIT_ON_FAIL | Used with reversal (void) requests. If set to 1, the system will automatically attempt a credit when the reversal request failed. |
| FORCE_CREDIT | Used for sending Force Credit transactions.  Force Credit is a type of transaction where the credit request is sent directly to the settlement file.
Merchants do not need to send the REQUEST_REF_PO_ID parameter on this type of request.
However, the FORCE_CREDIT parameter is required, together with the full credit card information.
*Force Credits are only available to certain Merchant Accounts. |
