setting silent post URL for multiple domains

I have multiple domains I will be using s2Member on and accepting payments through Authorize.net. Each domain requires a different Silent Post URL but Authorize.net only allows me to set one.

Example:

http://domain1.com/?s2member_pro_authnet_notify=1

http://domain2.com/?s2member_pro_authnet_notify=1

Since Authorize.net only allows one Silent Post URL what are my options? Can I create a third domain that I use for all payment processing? Would that allow the individual domains to validate properly? The domains would have different users and a user on one domain would not have access to the other domain without an account there.

Is there another option?

Hi Angel,

You may be able to use a similar technique to that which we’ve used for PayPal Pro multisite networks that require a central IPN processor script. Please the second paragraph in Dashboard -› s2Member® -› PayPal® Options -› PayPal® IPN Integration -> More information.
