At the moment I am adding the user to one group at a time using this endpoint:
PUT /{realm}/users/{id}/groups/{groupId}
In my use case it would be beneficial to perform the affectations in bulk, so far I haven't found a documented way of doing so, is there a way to do it? Thanks
PUT /{realm}/users/{id}
It's in the documentation, but it doesn't work.
I started discussion on github
You could try to update the full user data
PUT /{realm}/users/{id}
with a partial UserRepresentation containing a minimal json with "groups" array only ?
I see that nearly all fields are marked as optional: cfr https://www.keycloak.org/docs-api/12.0/rest-api/index.html#_userrepresentation
