[keycloak-user] Transferring social login from mobile apps to Keycloak

Hi, I would like to use Keycloak as a backend security and user management solution for my native apps (Android and iOS). In my native app, the user can register/login with Facebook/Google+ using the corresponding native SDK. After the login I get all desired user data and even the access token. Then I would like to create a user in Keycloak via the REST API with this social account. It should result in the same user data, like using the social login of the Keycloak's web login. Any ideas, how to get this done? Cheers, Artjom
