# Map a directory group to a role

`POST /v1/directories/{directory_id}/role-mappings` · permission `directories:write`

Maps a group of a SCIM directory (`directory_group_id`) to a role; members of the group receive the role in the directory's organization. The group must belong to this directory. The role must be an environment role or a role of the directory's organization. Mapping to a privileged role additionally requires `roles:write` and the mapping is created approved. A directory that is being deleted accepts no new mappings. At most 500 mappings per directory. The write is audited as `role_mapping.created`.

## Request

| Field | Type | Required | Description |
|---|---|---|---|
| `directory_id` | path | yes | SCIM directory ID (`dir_…`). |
| `directory_group_id` | string | yes | Directory group ID (`dsg_…`). |
| `role_id` | string | yes | Role ID (`rol_…`). |

## Response

`201 Created` with the mapping.
