Is client_id claim globally unique ?

[nemehta]

We are investigating LTI 1.3 standard and have found that for the auth request the tool is expected to save the Issuer=>Client_Id mapping provided during the app registration process. Since the 'iss' claim for launches through Canvas have common "canvas.instructure.com". Is it safe to assume the clientId is going to be unique across all tenants (in other words is client_id suppose to be globally unique) of canvas ? Or is the client_id just unique for the particular tenant ?

 @nemehta ,

First, I want to apologize for your question sitting in the community for so long without a response.

Second, it looks like you have stumped the Canvas Community.  Were you able to find an answer to your question? I am going to go ahead and mark this question as answered because there hasn't been any more activity in a while so I assume that you have the information that you need. If you still have a question about this or if you have information that you would like to share with the community, by all means, please do come back and leave a comment.

I was able to get an answer offline. ClientId is unique globally. Putting it here for future reference to anyone else. Let me know if there is a misunderstanding.
