Revoking Token in Keycloak

[AdigaAkhil]

Hello @ivangfr ,

Firstly, great project! loved it. It covers everything from the backend and front end.
However, I had some queries regarding Keycloak in your project.

As far as I have done research the only API to revoke a token is the /revoke API which looks like this

http://localhost:8080/realms/<realm-name>/protocol/openid-connect/revoke
Along with this URL we will also be using clientId,client-secret, token_type and the actual token we want to revoke.

My query is, if we use the PKCE apporoach there is no client-secret ,so how do we revoke the token since the client secret is not optional

The same query applies for the introspect endpoint as well

http://localhost:8080/realms/<realm-name>/protocol/openid-connect/token/introspect

Hi @AdigaAkhil

I believe I got it partially. The introspect endpoint is returning 403 and the revoke is working.

I've used the app of this repo.

Get JWT token

$ curl -i -X POST \
  "http://localhost:8080/realms/company-services/protocol/openid-connect/token" \
  -H "Content-Type: application/x-www-form-urlencoded" \
  -d "username=admin" \
  -d "password=admin" \
  -d "grant_type=password" \
  -d "client_id=movies-app"

Probably, there is some config we need to set for the client.
