How to Launch a Lincoln Speech from Canvas with LTI

My sample provider site has two Lincoln speeches which I use to experiment with LTI consumers. I signed up for a trial Canvas account yesterday and found out that the trial includes LTI consumer functionality. So, of course I started to add one of the Lincoln speeches.

However, when I setup the external tool in Canvas, I noticed that my sample provider site made it unnecessarily difficult by asking for the tool_consumer_instance_guid (Canvas does not expose that value to the user). So I removed that requirement. Yeah for owning the code! Once that was gone, it was fairly straightforward.

Here are (the now simple) steps to launch a Lincoln speech from Canvas with LTI.

  1. Login to your Canvas site.
  2. Select one of the courses.
