I've got Ubercart set up with Paypal Payments Pro and it is all working well, however, I want to set up the system so that when a payment is received (captured) in PayPal (after which the site successfully receives an IPN), an email is sent to our manufacturing plant to fulfill the order (including the order details, shipping address, etc.).
I am aware of hook_order but I'm not sure how to use it in this scenario (i.e., upon IPN), or whether there might be an easier way to accomplish this (without code, i.e., using Actions). It is OK if we have to code it, that is not a problem. Only want to know my options.
