I would like to use the Microsoft Power Platform to connect to Canvas LMS. Specifically, I want to download Course Syllabi and save them in Sharepoint. I have some limited experience with Power Platform's REST API's. I created an API Developer Key in Canvas. It's not clear to me what specific requests I need to make in order to get an access token. I found some documentation on Canvas OAuth2 and Canvas developer keys but nothing that specifically tells me what I need to send to get the token.
Thanks!
