Hi,

I have developed a online software selling website. I have used ubercart file download with ubercart product keys modules. I want to provide download link and product activation key in the order confirmation mail only. I hacked the customer order template according to my needs. Now i want to disable the other mails. I need only one mails to be sent, which will include normal billing and shipping details as given by order confirmation email along with download link and product key.

How can i invoke/load that data in customer mail php template? i am using ubercart 2.4
