Payment Express

Hello, hope someone can help me out with setting up Payment Express. I have a developers account at Payment Express (DPS), and have entered my username into the plugin.

First question is the password the account password or the pxpaykey? I have tried both and always get the error below when trying a test transaction with one of the test credit card numbers.

Error : 0DECLINED The transaction was Declined (U5)

Second question is, I thought it take me to a DPS hosted web page to enter the credit card details, not entre them at my web page.

Any help would be appreciated. Thanks

The hikashop payment express plugin integrates the pxpost API of payment express: www.paymentexpress.com/Technical_Resources/Ecommerce_NonHosted
Please check with payment express support that you're using the correct username/password for it.
DPS is another API that is not supported by the plugin.
