keycloak Invalid parameter: redirect_uri

Question

When I am trying to hit from my api to authenticate user from keycloak, but its giving me error Invalid parameter: redirect_uri on keycloak page. I have created my own realm

Answer 1

Go to keycloak admin console > SpringBootKeycloak> Cients>login-app page. Here in valid-redirect uris section add http://localhost:8080/sso/login

This will help resolve indirect-uri problem

Answer 2

It seems that this problem can occur if you put whitespace in your Realm name. I had name set to Debugging Realm and I got this error. When I changed to DebuggingRealm it worked.

You can still have whitespace in the display name. Odd that keycloak doesn't check for this on admin input.

Answer 3

This error is also thrown when your User does not have the expected Role delegated in User definition(Set role for the Realm in drop down).

Answer 4

I faced the same issue. I rectified it by going to the particular client under the realm respectively therein redirect URL add * after your complete URL.

Answer 5

For me, I had a missing trailing slash / in the value for Valid Redirect URIs
