Hey everyone I am creating an LTI1.3 Tool and I have a question surrounding t he names and roles lti service. As far as i know, there are 2 names and roles api endpoints in canvas: /api/lti/courses/:course_id/names_and_roles /api/lti/groups/:group_id/names_and_roles However, how does one find all the group_id's in each class, to call the /lti/groups request? I want to keep my tool as lti1.3 and non-platform specific, so I'd rather not use Canvas specific api requests. Do any of you fellow developers have any ideas, thoughts or solutions regarding this problem? I'd be happy with any help. Thanks and regards, Atli Gislason

I just realized that the id_token from the openid login does give the following endpoint path for the names and roles service This solves my issue, apologies if I sounded rude in my question above. Best regards, Atli Gislason

Hi everyone I am creating an LTI 1.3 Tool that calls Canvas's names and roles service, specifically the following endpoint /api/lti/course/:course_id/names_and_roles One would assume that :course_id in this endpoint could mean both Canvas's id for the course as well as the LTI 1.3 context_id that is returned in the request. However when using the LTI1.3 course id, the request simply returns 404 resource not found. See here the difference: Calling with ID = 1. (Canvas course ID) Calling with the LTI1.3 context id Is this the intended outcome? Is this a bug? I don't understand why this wouldn't support the context_id since using Canvas's own id just means more overhead for the developers. Great thanks if any fellow developer can provide any help. Regards Atli Gislason

Hi everyone I have created an LTI 1.3 developer key which has privacy level set to public. I now attempt to call the names-and-roles-membership, but it only returns 3 values per member as if it were private. I call the API with the client_credentials JWT token, using api path: /api/lti/courses/1/names_and_roles. Why do I not get more info per student? Regards Atli Gislason

Hi William I have a very similar issue, I feel as if there are so many Id's for each user in canvas. However I hope to help you with something that I have found out. If you initiate the login through openid, and decode the id_token, the sub field should at least tell you what the name-and-roles-membership id of your user is. See below: The "sub" field for the id_token (decoded on jwt.io) and the user_id for the first member is the same id. This is something I just found out, I know it might not fix your problem completely, but it could help Regards Atli Gislason

Additionally I'd like to ask if there have been any updates on when Canvas will release LTI1.3 out of beta and implement OpenID login for example?

Hi everyone, I am developing a tool for Canvas that uses LTI1.3. I have implemented the client_credentials process for my app, however the client_credentials process does not give me any way to identify the user that started the request. I would like my app to receive user info (just name or id), and list their classes and send grades and create assignments, etc. How is that done with client_credentials or another LTI1.3 compliant manner? Great thanks to this developer community, it has been fantastic for developing this webapp.
