error 18

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.

This parameter allows to transmit the buyer’s name. It is a deprecated field that can be replaced by the vads_cust_first_name and vads_cust_last_name fields.

The length of the vads_cust_name must not exceed 127 characters.

Otherwise the payment gateway returns an error.
