Creating specific fields according to your requirements
The merchant can transmit specific information in the payment form. For example, the merchant can add information in the payment confirmation e-mail that he or she will receive.
This information will be visible in the Back Office, in transaction details (Extras tab), and will also be returned in the notification URL.
The name must begin with vads_ext_info to be taken into account.
