Thanks James, I will happy for the one additional clarification. I use 2.2.1 and the following tutorial: https://keycloak.gitbooks.io/server-developer-guide/content/v/2.2/topics/... Where can I find the description of the required permissions? The link in the document points to the content page: https://keycloak.gitbooks.io/server-adminstration-guide/content/ Best regards, Michael ________________________________ From: James Falkner <jfalkner(a)redhat.com&gt; Sent: Thursday, October 6, 2016 4:25 PM To: Michael Furman Cc: keycloak-user(a)lists.jboss.org Subject: Re: [keycloak-user] Newbie API question Michael Furman<mailto:michael_furman@hotmail.com> October 6, 2016 at 2:40 AM Hi all, I have started to learn Keycloak and I need your help. 1. Is it possible to resister a new client using REST API? http://www.keycloak.org/docs/rest-api/ I want to use the static client registration. Yes, it's possible<http://www.keycloak.org/docs/rest-api/#_create_a_new_client> - for example, this is how the JBoss EAP/Wildfly adapter does automatic client registration - it does a POST to /admin/realms/<realm-name>/clients with a json blob that looks something like { "clientId": "some-client-id", "rootUrl": "", "adminUrl": "https://some-host:8443/"<https://some-host:8443/>, "baseUrl": "", "secret": "", "redirectUris": [], "bearerOnly": true, "publicClient": false, "protocol": "openid-connect" } -James
