I think I'm missing something sort of fundamental. I've used the API before (written some nice command line tools). I've taken the LTI course, and I'm at the point where I have OAuth working and I can get my LTI app to show up in the menu in canvas and have it appear inside an iFrame.
So my question is:
How does my LTI app query/get stuff out of canvas?
Am I supposed to use the API as I have been doing with my command line tools? If so, what APIKey do I use, or is there someway to use the API with the same credentials as the incoming user? Or is there an entirely different set of commands I can do with LTI.
