  14. Take note of the URL of the page you are redirected to. It should be like https://lti-ri.imsglobal.org/lti/tools/5852. The number at the end, 5852, is the tool ID.

  15. Again edit the xblock. Set Tool Public Key Mode to Public Key   

  16. Copy public key from https://lti-ri.imsglobal.org/keygen/index and paste in Tool Public Key.

  17. Create tool launch URL as https://lti-ri.imsglobal.org/lti/tools/<tool_id>/launches where tool_id is what we extracted above. Paste the URL in Tool Launch URL.

  18. Create tool initiate login URL as https://lti-ri.imsglobal.org/lti/tools/<tool_id>/login_initiations. Again, replace the tool_id with what we extracted above. Paste the URL in Tool Initiate Login URL.

You need to launch the tool from the LMS, not from Studio.

Points to incorporate:

  • Launch from new window.

  • User same browser session for IMS and Open edX for logged-in testing.
