[keycloak-dev] Trying to use Admin WS but got 401 Unauthorized

Hello you all, I need to configure realms in Keycloak through 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
