Is it possible to run a script upon a successful payment? What I'm trying to achieve is taking the user data used during signup and posting it to a second database using a simple post after a successful payment. I have an idea where and how to do this however I'm not sure how to carry over the data collected during the signup process.
Normally you would do this as a plugin so that the data would be updated, if you want one developed you can contact me over at JLogica.
