OAuth Invalid/Unknown Client Error
Are developer credentials from Canvas limited to a particular Canvas shard?
Okay, so this one has really stumped me. I have some LTI applications that are being used by a variety of institutions on a variety of Canvas instances. I was working with an institution to install one of the tools and I keep getting the following error from the https://<institution>.instructure.com/login/oauth2/auth page:
"error_description": "unknown client",
"message": "invalid client_id"
Has anyone encountered this before or know how to go about diagnosing the issue?
Here is some additional information that may be helpful:
- My client ID is correct in the URL.
- My developer credentials came through Instructure (not those you can now generate at the institution level).
- My developer credentials have been used successfully in 6+ different Canvas instances.
Thanks in advance for any help.
