Sujani,
Adroll will make at least two requests to send the tracking data. The first is a request to pull in a JS file. This is the request you are showing in your last comment. However, this is not the request that will have the data populated in it.
The second request is the one you want to look for. It should look something like the following:

If you do not see this request being made or this exists but the data is not there, I would suggest reaching out to your Account Manager with steps to reproduce. This is working as expected in my local sandbox, but without being able to place an order on your site to reproduce it is difficult to say what would be happing.
