LTI 1.3 - Page not found error

[KylanJohnson]

I am getting a page not found error, while trying to link resources using an external tool when testing for Canvas LTI 1.3 integrations.

This is the url, for which Canvas was throwing a 404 page not found error.

https://canvas.instructure.com/api/login/oauth2/token?lti_message_hint=eyJ0eXAiOiJKV1QiLCJhbGciOiJIU...

Thanks

Do you have a screenshot of the 404 error? 

It's hard to say where the error might be without a screenshot or additional details because it could be caused by the LTI provider.

What is the URL of the page reporting the 404 error?

https://canvas.instructure.com/api/login/oauth2/token?lti_message_hint=eyJ0eXAiOiJKV1QiLCJhbGciOiJIU...

Do the login_hint and lti_message_hint parameter values match those you received from Canvas?  Is the URL of "https://psc27765.illuminateed.io/qa27765/ltiadvantage/assessment/" registered as a redirect URI in Canvas?

I have figured out what is the issue is. I was using the wrong url. Instead of , https://canvas.instructure.com/api/lti/authorize_redirect, I was using https://canvas.instructure.com/api/login/oauth2/token.

Issue got resolved.

Thanks
