Yes, I am using this contribution. However, what I want is a seperate email to be sent. Basically, what they are purchasing is an activation code. Once the payment is confirmed, I want to send them the activation code in an email. I have the coding done for the actual email and stuff. I just don't know where to add it so that it is sent at the same time as the invoice. Where I have it now is in the checkout_process.php file. If I ordered through say, Cash on Delivery, it would be sent at the same time as the invoice. However, when I order it through this module, it doesn't get sent.
