# Create an environment role

`POST /v1/roles` · permission `roles:write`

Creates a role in the environment's role catalogue. The response carries an `ETag`; the write is audited as `role.created`. `Idempotency-Key` is optional.

## Request

| Field | Type | Required | Description |
|---|---|---|---|
| `key` | string | yes | Lowercase letters, digits, `_` and `-`; 1–64 characters; unique in its scope and immutable. |
| `name` | string | yes | Display name, up to 128 characters. |
| `description` | string | no | Up to 1024 characters. |
| `is_privileged` | boolean | no | Marks a privileged role: in self-service only a member holding the organization admin role (`org_admin_role_id`) can assign it, and mapping an external group to it requires `roles:write` and approval. |
| `assignable_in_self_service` | boolean | no | Defaults to `true`, also for a privileged role. |

## Response

`201 Created` with the role.
