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.
