Hi @InnovationLLC,

Unfortunately, I don't believe developer LRI (or API) keys are available on the free-for-teacher Canvas version.  As a developer, there are two main options to test integrations with Canvas:

• Become an Instructure partner.  This would be the most "official" way and offers support from Instructure as well, but it does come at a cost.
• Use the open-source version of Canvas.  This requires a server environment and server admin knowledge, and doesn't have identical features to the Instructure-hosted web version of Canvas, but it's pretty close for most LTI testing.

I hope this info helps!
