I am utilizing a wordpress plugin known as 'Paid Subscriptions Pro' (see here). I have to personalize this wordpress plugin to be able to not just pass information to, but additionally receive information from this. I've read here concerning how to pass custom variables in to the script however, I am unsure where this script is certainly going when the user submits a payment form and therefore cannot learn how to obtain a response in the script.

Basically, I would like the script to make contact with MY PHP script which is another PHP script in the wordpress plugin itself when the payment went through effectively. This is exactly what I am talking about when I only say "receive information in the script".

If anybody includes a minute to mess with this particular script, and look for the code behind it, I'd like to hear that which you all have to say of this.
