error 08

In PRODUCTION mode, if your buyer gets an error message such as:

An error occurred during the payment request, please make sure that the posted parameters match the ones specified in the documentation.

It becomes impossible to make the payment and the transaction is definitively lost.

You will receive an email notification containing the form that the gateway was unable to process and the value of the invalid field.

We invite you to check the following reason(s) to resolve the issue:

The vads_payment_cards value is invalid.

The vads_payment_cards field is optional and defines the card types which will be offered to the customer (MASTERCARD, VISA, MAESTRO, VISA_ELECTRON, etc.).

Example :

If you want to offer VISA and MASTERCARD only, you have to populate the field as follows:

vads_payment_cards =VISA;MASTERCARD.

Make sure that you respect the following rules.
  • The type of card must be known (CB, VISA, MASTERCARD, etc.).
  • The separator between the different types of card is ";".

By default it is recommended not to post this parameter.

If the value is valid please contact E-commerce customer service.
