Updating tracking number through API

I am having some serious trouble finding out how to update tracking number on a order through the API.

I am using the helper class stickied in the forums to do this. I have tried some different things but to no avail. If anyone has done this before, either with clean php cURL or via the helper class, please post an example. I am completely stuck right now at this problem.

that would be a good idea,

i see from the undocumented api docs, that you can query order, but create is not detailed, therefore update is also.

why not just do it the ole fashion way , you have the orderid just create the db fields
