PHP integration, keep getting page with that message
This message appears when your integration is in “Test” mode.
See information on test mode here
After creating a transaction ONLY THE MERCHANT ACCOUNT USED TO CREATE THE INTEGRATION can login and Fake a Payment. Any other users will get a message saying the merchant is in testing and they cannot proceed with payment.
In order to change it from Test to Live, you need to have completed a successful Test transaction, then you can contact [email protected] and request for your integration to be set live.
