Need help 2 websites 1 payment gateway

Hi All
I hope i have opened this thread in its correct location.

I have a merchant account with netbanx and am in the process of integrating it into my site. I went through a company called card save and they advised me that I will be able to use the service on another website also. Netbanx have informed me that they will only let my current URL pull up the script and if any other URL tries then it will receive an error message.

I have since been in contact with card save and they advised me that as long as your 2nd website is using the same cart so in my case zencart which they both are, then everything will be fine. They went on to advise that I will need to have my 2nd website direct to my current website to pull the script. Im not sure how I can do this and would appreciate some help.

I hope this makes sense.

thanks alot

This can be complicated. You might want to start by taking a look at the multisite add-in which addresses many of the issues that would need to be solved.

Hi Thanks for your reply
The link you provided is for a mod to add to zencart. I couldnt find a support forum. Just wondering if there is one.

Also it talks about having the same template on each cart. Can I not have everything different but have the website just call the netbanx script?

Will I be able to offer different products on each site or will the original url have to offer all the products the other site will?

thanks
