I found one that looks like it might do the job at www.multipleipn(dot)com (no affiliation), but was wanting a little more input from other Warriors that might be a little more experienced in running one of these.
The reason why I need this is because I'll be running 2 membership sites and need to use an IPN for one of them without screwing up the return URL for the other membership site.
If I were to set just the one IPN, wouldn't that override where the sign ups to the first membership site go as it's only set to use a basic return URL?
And, is anyone familiar with the Multiple IPN script or using it?
Does it work well?
Any input would be much appreciated.
