Error when payment processing using Realex

I am working on payment processing using Realex with GWT

But at the last step it gives me following error message

Using test system. Please u开发者_如何学运维se pre-approved test cards ONLY

Please help me.

Your account is in test mode so you must use test credit card numbers. These are provided by Realex.

Most payment processors i've seen use one of two approaches:

• Have a "test mode" setting in the account, and a "test mode" variable in the gateway, and only consider the charge live if neither one indicates test mode. (IIRC authorize.net works like this) OR
• Have different URLs for test vs live charges. (I'm thinking Paypal works like this...at least their IPN stuff does.)

Make sure you're using a "live" url, and that the account itself is not set for test mode.

You can find Realex's test card numbers here. Make sure you only use the test cards in test mode, pointing at the sandbox address - https://api.sandbox.realexpayments.com/epage-remote.cgi
