[ARCHIVED] LTI tool provider registration issue - please help

[abdul]

Hi,

I am trying to create an LTI Tool provider integration of our tool for Canvas. However, we seem to have hit the wall when building the registration service. Would be greatly appreciate for any pointers or sample apps that can help us guide through this integration. Some technical information...

Our LTI interface is build in Java. The registration endpoint as expected was successfully called by Canvas, with all expected headers. However when we make the ToolProxy registration request, we receive 401 unauthorized response. It is possible that the request may be invalid but we are struggling to find what it might be, as key, secret and data is supplied as suggested.

There does not seem to be much help online towards LTI registration implementations. Can you please point me to any resources that can help us resolve this Oauth1.0a interaction with Canvas.

If you're struggling with a ToolProxy registration I'm guessing you're building a LTI 2.0 tool is that correct? If so there is a general move away from LTI 2 as it was never well adopted and the LTI 1.3 specification sort of supersedes it (although it offers different functionality).
