error 43

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 format of the field is incorrect.

The vads_cvv field allows to transmit card security code (in case of a silent payment). It must consist of numeric characters with a variable length up to 2 characters (n..4).

Its length can vary between 3 and 4 digits depending on the card type.

Check that the value entered in the form is correct.
