I am hoping someone out there can help me here! The reward module works just fine for me - but I have a situation where users can buy a service from a 3rd party application and will not necessarily visit Zen cart during that purchase (we lie in an express world now - no time to check in and all that!!!). I basically have two choices:-

1) Update Zen Cart tables directly. ( I need to confirm the exact tables to update for that user - dont want to screw the dB up)
2) Check them in into the checkout module automatically. This is my preferred approach, but I need to know
(a) How to log them in behind the scenes
(b) How to add the item into their cart and then land them into the pre-checkout page.

This will give them the desired option to checkout (and pick up those valuable points) or spend more time shopping - before checking out.

I hope this all makes sense? Can anyone help? By the way, the rewards module is really really cool!
