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!

  • The question is how to validate JavaScript Web Tokens on other web apps. Do I have that right?

  • @cilefen Not quite. I want to validate access tokens I've received from Drupal/Simple OAuth module. I receive an authorization token after the user logs in. I can then exchange that for an access token and refresh token. I want to validate the access and refresh token. Jan 30, 2023 at 1:45
  • OAuth sends validity times with the tokens. But you wish to test them further without making an ordinary API call (like a request for some data with the access token), or request a new access token (with the refresh token), correct? The question is whether or not OAuth requires a validation API, does this module provide one, yes?

  • @cilefen That is precisely correct. I'm hoping there is a separate API call only for token validation. Jan 30, 2023 at 14:11

    The routes in that module are git.drupalcode.org/project/simple_oauth/-/blob/5.2.x/… and the implementable OAuth 2.0 endpoints are documented in this RFC: rfc-editor.org/rfc/rfc6749.

I am fairly sure the answer is "no". There is no such route provided by the module.

At this stage this looks like a feature request for the module.
