Trying to log in to Keycloak Admin WS

Question

I need to configure realms in Keycloak by the Admin WS accessible at the path

http://KeycloakServer:8081/auth/admin/realms

So in Postman I run the following request

URL: http://KeycloakServer:8081/auth/admin/realms

Method: POST

Body:

{
    "enabled": true,
    "id": "TestRealm",
}

I get a 401 Unauthorized response, so I think it is necessary to authenticate to the Admin WS. But in the docs I cannot find any information about the type of authentication required and the syntax. Do you know how to authenticate to the Keycloak WSs?

Thank you

Answer 1

Do a POST request to https://hostname:8080/auth/realms/master/protocol/openid-connect/token

Sets the Content-Type to application/x-www-form-urlencoded

and put the following in the body:

username=<username>&password=<password>&client_id=admin-cli&grant_type=password

Answer 2

This will do the trick for you. Do a post on

URI - /auth/realms/master/protocol/openid-connect/token

with Headers as below

1. username=<admin username>
2. password=<admin password>
3. client_id=security-admin-console
4. grant_type=password
5. Content-Type=application/x-www-form-urlencoded

This will return you a JSON, with access_token in it. Take the token and use it as the Authorization Bearer Token in your request. It should work.

Let me know if you face any issue.
