I am using the OAuth2 authorization code grant with the Simple OAuth module. Everything is working, however I would like to be able to validate access and refresh tokens from my frontend NodeJS server. Is there an API endpoint to which I can send a token to, and in the response I get information about that token (aka token introspection)? For example, a response telling me the token is expired.
Thanks for all the help in advance, and let me know if I need to clarify the question in any way!
