error 10200

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 e-mail 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 to resolve the issue:

The token ID already exists.

You have requested the creation of a token, and have provided the token ID (vads_identifier field) to be created in your payment form.

However, this identifier is already used by another token, thus your request to create a token cannot be completed.
