How can validate access_token?

hi everyone
I have done the flow oauth2 correctly.
I have my access_token Bearer and would like to validate it.

how do i do that?

in addition it seems that access_token does not comply with the standard RFC 7515

why?

Hello @niko-olas,
You can use the /v1/users/me endpoint for this. If you want to see the authorization, you can also get the scope values ​​when renewing the token.
