error 03

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(s) to resolve the issue:

The transaction id has not been sent to the payment gateway.

The transaction ID is mandatory.

Make sure that the transaction ID is sent to the payment gateway.

The vads_trans_id field must be present and properly valued.

The format of the field is incorrect.
The transaction ID must consist of 6 alfanumeric characters chosen from the following list:
  • any digit between 0 and 9,
  • any lower case character from "a" to "z",
  • any upper case character from "A" to "Z".

Example: "aS76J3"

An identical transaction id has already been sent to the payment gateway on the same day.

The transaction identifier absolutely must be unique within the same day (from 00:00:00 UTC to 23:59:59 UTC).

If two identical transaction ids are sent to the payment gateway by the same shop on the same day, then the gateway will return an error for the second form.
