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
