How to integrate a gateway service using Authorize.net

[John M]

I have been very successful implementing the ps_authorize.php gateway whent eh client uses an account from "authorize.net" however I  have a client that signed up with Primus, a third party gateway service and I am unable to get the gateway to work.  They sent me a transact.dll link that they said to replace mine with in the script however it is still not working.  Furthermore I am not sure now what to do with the transact key and API login ID that is being asked for in the script admin section.

I could sure use some help here if anyone knows how to overcome this issue.

Thank you

JM

Hi,
I need to install Authorize.net for my client but I have never used any gateway except for PayPal. Can you please point me to the right information and the link to download the actual script that I can install in VM?
Thank you for your prompt response!
Kindest regards..
