How to add Keycloak realm role to group via REST API - keycloak

Question

I want to assign the realm role "TEST_ROLE_123" to a group, I am using
PUT /admin/realms/ataccamaone/groups/{group-id}
{
"realmRoles":["TEST_ROLE_123"]
}
I got group-id from /admin/realms/ataccamaone/groups/
However I get the response 204 No Content and in the Keycloak console I do not see the assignment.

Answer 1

I tried to reproduce your problem and find that PUT /admin/realms/ataccamaone/groups/{group-id} can only edit group name.
Inspect into "Network" tab of browser, I see it uses another URL to map roles to groups. And steps to do this via Admin REST API are:
Obtain PAT as described in https://www.keycloak.org/docs/latest/authorization_services/index.html#_service_protection_whatis_obtain_pat section
Following steps use this PAT as Bearer token (in "Authorization" header). I guess you've already got this.
Call GET http://localhost:8080/auth/admin/realms/realm1/roles to get list of roles, including their name and id values.
Call GET http://localhost:8080/auth/admin/realms/realm1/groups to get list of groups, including their ids
Call POST http://localhost:8080/auth/admin/realms/realm1/groups/{group-id}/role-mappings/realm with following body:
[
{
"id": "9083cac3-4280-497d-b973-7713a5fb12b4", // role-id
"name": "secretary" // role-name
}
]
Call DELETE with URL and body same as step 4 to remove roles from group.

I've faced same issue and corrected it with using a GROUP, Basically I've added the preferred ROLE into the User Groups ROLE LIST and used that specific user group while creating the user via REST API.
Eg:- ADMIN_USER_GROUP -> INCLUDED ('ADMIN_ROLE')
Then User creation API Request should be like below,
{
"firstName": "Sergey",
"lastName": "Kargopolov",
"email": "test4#test.com",
"enabled": "true",
"credentials": [
{
"value": "123"
}
],
"groups": [
"ADMIN_USER_GROUP"
]
}
