Greetings community, the details that what happens.
I created my personalized payment module, which applies a credit card.
When doing the trax, it returns the data of the transaction to an external file called "callback.php".
So, what I want is that data that I have in the file callback.php, show them in the mail of complete order, which reaches the user.
So that the user or the user has a backup of the data of their purchase and transaction.
I hope I was clear.
thanks for your help
