Trouble connecting with Authorize.net from osCommerce (using AIM)

[jmschultz13]

I'm trying to set up Authorize.net (AIM) within my new OSCommerce site. It keeps returning the error 'There has been an error processing your credit card. Please try again and if problems persist, please try another payment method.'

Please help.

Tech support that I need someone to help me find the response string so that they could further troubleshoot. I have no idea how to do this.

You can login to your authorize.net merchant account, and find the settled or unsettled transaction and see what the response are. If there isn't any, it probably your osCommerce authorize.net settings is wrong.

I was able to log in and check and there were no transactions showing. What osCommerce settings for authorize.net do I need to troubleshoot? I just doublechecked the API login ID and I reset the transaction key and MD5 hash.

What else should I look for?

Since it probably a settings issue on osCommerce, have you try their help?
