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 via the Merchant Back Office of the payment gateway.
From now on, transactions are available via the Merchant Back Office (Management > Transactions, in the left top corner of the interface).
Verify that the IPN provided in the Merchant Back Office functions correctly without clicking the Return to shop button.
