Keycloak: All API response with 404

Question

I followed this tutorial to setup Keycloak and create user but the response for the step of Generating Access Tokens With Keycloak's API 404. I'm using Keycloak version 18.0.0

In the logs of keycloak I found this error

2022-06-12 23:59:57,177 DEBUG [org.keycloak.services.error.KeycloakErrorHandler] (executor-thread-3) Error response 404: javax.ws.rs.NotFoundException: RESTEASY003210: Could not find resource for full path: http://localhost:8080/auth/realms/test/protocol/openid-connect/token

Without your endpoint-code it is hard to determine. Maybe the REST-Method is not post? Or something in the path is wrong? — codlix, Jun 12 '22 at 22:01
The URL for generation token in Keycloak is http://localhost:8080/auth/realms/ {{realmName}}/protocol/openid-connect/token — Sara Selim, Jun 12 '22 at 22:04
Are you sure it is configured to run on port 8080? the tutorial is running on a different port — sinanspd, Jun 12 '22 at 22:04
I can access the admin console using this url http://localhost:8080 — Sara Selim, Jun 12 '22 at 22:06

From keycloak 17+ there are changes in resource or token URIs. Try removing auth from your request URL.

If you are using Keycloak version < 17

curl -k -H "Content-Type: application/x-www-form-urlencoded" -d "client_id=your-client" -d "username=some-user" -d "password=hardpassword" -d "grant_type=password" -X POST http://localhost:8080/auth/realms/yourrealm/protocol/openid-connect/token

If you are using Keycloak version > 17

curl -k -H "Content-Type: application/x-www-form-urlencoded" -d "client_id=your-client" -d "username=some-user" -d "password=hardpassword" -d "grant_type=password" -X POST http://localhost:8080/realms/yourrealm/protocol/openid-connect/token

404 Error means the URL of the resource does not exist.

You did set in Headers instead of Body. Move the Key & Values to Body.

In Keycloak version 18

You can verify Token URL by click "OpenID Endpoint Configuration" link

It will show Token URL

In Keycloak version 21

OIDC Well-Known Configuration Endpoint

Returns the OpenID Connect configuration values from the Keycloak's Well-Known Configuration Endpoint

GET /.well-known/openid-configuration

http://localhost:8080/realms/[your realm]/.well-known/openid-configuration

Token End Point

http://localhost:8080/realms/[your realm]/protocol/openid-connect/token

Get Access Token by Postman.
