Causes of the vads_trans_id error

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

The transaction ID is mandatory.

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

The vads_trans_id field must be present and properly valued.

The transaction id is not composed of 6 digits or is higher than 899999.

The transaction ID must imperatively be a number between 000000 and 899999.

Example:

23 is not a valid transaction ID, if the transaction number is lower than 100000 you have to add the corresponding number of ZEROS before the number.

000023 is a valid transaction ID.

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

The transaction ID must imperatively be unique on the same day (based on the DATE field i.e. according to the UTC time zone).

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

If you have confided the administration of your shop to a WEB agency, send them an e-mail with the received notification.
