Keycloak REST API with Postman

Demonstrate how to use Keycloak's admin REST API with a postman client application.

For invoking a REST endpoint, client application should obtain an access token. After that the access token should be added to the authorization header of each REST API call as a bearer token.

OAuth 2.0 protocol is used to obtain access token.

Keycloak OIDC token endpoint: http://{HOST}/realms/{REALM_NAME}/protocol/openid-connect/token

Base URL for REST API: http://{HOST}/admin/realms​
(Host: localhost:8080 BasePath: /admin/realms)

Example for listing users: GET http://{HOST}/auth/admin/realms/{REALM_NAME}/users

Hi Sir, Please let me know how do I create a new client in Keycloak through postman.

For the 403 error I have a valid access token and also assigned enough roles to the client to query the second endpoint to fetch users.yet it is showing 403 forbidden error.what am I missing out or need to check?

Hello friend, do you know how I could use the logout endpoints, perhaps change the password for a user, with a public client?

[DanielRamos-ovmb]

Hello, In my case, I don't know why the 401 error appears, if I have the header and the access token not expired. If you can help me please

Do you know how to add federatedIdentities attribute to the /users endpoint ?

[damiankozakiewicz]

While sending the Request to fetch the user List, I get the following Error: "RESTEASY003065: Cannot consume content type" - I tried to set the content-type as application/xml but it is not working. Do you have any idea on how to solve this?
