The information seem to be vague at best, Ive tried searches and have only turned up results that are years old and don't seem to be related to the problem I'm having. So here we go.....
Downloaded and installed the latest certified SIM version from the addons for ver 2.3.
Set up the information I have been using with AIM(now disabled while I set up SIM) for years and enabled the module in a live environment.
created an order and checked out, it redirects me to authorize.nets form and I enter real credit card info(no test numbers, its live) and click the pay now button.
the site redirects me to my website.com/login.php
upon checking the transaction is captured/pending settlement telling me the payment was made but not returned to my website and added to the order table
Currently I have not set the Default Receipt URL and the Default Relay Response URL as I have tried it several ways and none have worked so far.
I can use AIM just fine but want to avoid some of the PCI headaches by doing this offsite.
Running out of ideas so if you have any insight please share, yes I have read a lot of the threads regarding the settings and seen it several ways and have tried them all.
