Keycloak - PATCH user attributes through REST API

Question

I am using Keycloak docker image 21.0.2 (the latest one).

I make a PUT request to this URL: http://localhost:8080/admin/realms/custom-realm/users/14905db1-5229-4110-bfbb-df13845a4f52 and with this JSON body to edit a user's attributes:

{
    "attributes": {
        "organization_id": "1"
    }
}

The problem is that this wipes out all user attributes and I want it to keep the old ones as they are used for other functionalities and cannot be wiped out.

I just want to append or replace 'organization_id' value in the list of user attributes.

I think it should be a PATCH request but Keycloak doesn't have one for users. Is there any way to make this work?

I tried to update user attributes through the ADMIN REST API but I think a PATCH method is missing...

Answer 1

I had the exact same issue and i finally resolve it by fetching first the information of the user and made a custom merge when updating the user with the keycloak admin client. It's not a fancy solution, but Keycloak at this date does not provide a way to partially update the user.
