Where to put tracking codes?

Hi all,



Just need to know where to place my comparison shopping website tracking codes.



I’m told the codes need to be placed on the “Thank You” page, that being the page after a sales has been successfully processed.



Thanks.



MADT.

It is placed in the order page about half way down. It will show up in the invoice in the top right.

Is there a way to make the email tracking number clickable like what shows up on the web?

Right now, the tracking number just prints on the upper right of the email invoice but it is just text.



When I go check order status online, the tracking number is clickable which is great.
