Making a first payment in production mode
It is recommended for the merchant to make a real transaction to verify that all of the components of the production environment function properly. Afterwards, you will be able to cancel this transaction in the Back Office of the payment gateway.
The Back Office is accessible at the following address: https://secure.payzen.eu/vads-merchant/.
From now on, transactions are available via the Management > Transactions menu, in the left top corner of the interface.
Verify that the IPN provided in the Back Office functions correctly without clicking on the Return to shop button.
