To use the split of credit and debit cards via e-Commerce, you need to include the CREDITDEBIT parameter in the hidden fields that you send to the orderstandard(_UTF8).asp payment page.
||"C": credit card
"D": debit card
This field has to be included in the SHA-IN calculation
Related error: When the buyer selects the debit card method but next enters a credit card number, an error code will be returned: "Wrong brand/Payment method was chosen".
For more information, go to e-Commerce.
If the payment is successfully processed with the CREDITDEBIT parameter, the same parameter will also be returned in the post-sale feedback.
However, whereas the submitted values are C or D, the return values are "CREDIT" or "DEBIT".
You will also find these values in transaction overviews via "Operations > View transactions" and "Operations > Financial history", and in reports you may download afterwards (cf. Reporting).
