Hi I would like make a Rest Get inside a custom authenticator. I can add RestTemplate dependency. but i would like ask if there’s a native module in keycloak to make the Rest call. Thanks ---

I’ve never used it from a custom authenticator or other extension, but it looks like the JBoss RESTEasy ([https://resteasy.github.io/](https://resteasy.github.io/)) client is included in Keycloak. ---

I’m not quite sure what you ment by ‘custon authenticator’ but I can guess you ment for a custom rest API extension to keycloak. > **[Cyben/keycloak-ezgroups-custom-admin-api](https://github.com/Cyben/keycloak-ezgroups-custom-admin-api)** > > This is an extension for keycloak's admin resp api You could look at this repo, I have implemented an extension that requires specific permission, this is still in progress but it works so check it out.
