Im currently building an application which involves with multiple LMS platforms and include Canvas too. Therefore I need Oauth integration with other services access enabled developer key to test the application functionalities. How can i get the developer key without registering to the partner program because i havent fully implmented the application yet so i cannot provide any application URL or anything releted production apps. Im also not involved with any institutions to get a developer key from an admin account of a institution. So please help me figure out how i can get the developer key and credentials to test my application.
