# Replace the roles of a membership

`PUT /v1/organizations/{org_id}/memberships/{membership_id}/roles` · permission `organizations:write`

Replaces the membership's manually assigned roles with `role_ids` (an empty array removes them). Roles granted by IdP mappings or directory sources are not changed. If `role_version` is given it must equal the membership's current `version`, otherwise `409 conflict`. The last admin's admin role cannot be removed. The write is audited as `organization_membership.updated`.

## Request

| Field | Type | Required | Description |
|---|---|---|---|
| `org_id` | path | yes | Organization ID (`org_…`). |
| `membership_id` | path | yes | Membership ID (`mem_…`). |
| `role_ids` | string[] | yes | The full set of role IDs (`rol_…`), at most 50. |
| `role_version` | integer | no | Expected membership `version` (1 or more). |
| `revoke_sessions` | boolean | no | Default `true`. Chooses whether removing a privileged (`is_privileged`) role revokes the user's refresh token families in this organization context (plan §17.4); `false` turns this off. In this release the choice is only recorded in the `revoke_sessions` metadata of the `organization_membership.updated` audit record and no session is revoked; the revocation is planned (`planned`) in the authentication service. |

## Response

`200 OK` with the updated membership and its `ETag`.

## Errors

| HTTP | code | When |
|---|---|---|
| 404 | `not_found` | The membership does not exist in this organization. |
| 403 | `role_not_assignable` | A role is not an environment role or a role of this organization. |
| 409 | `conflict` | `role_version` does not match the membership's current version. |
| 409 | `last_org_admin` | The change would leave the organization without an active admin. |
| 422 | `validation_failed` | `role_ids` is missing or invalid, or `role_version` is below 1. |
| 401 | `unauthenticated` | The credential is missing, invalid or revoked. |
| 403 | `insufficient_permissions` | The credential lacks the required permission. Assigning a privileged (`is_privileged`) role also requires `roles:write`; without it nothing is written and `required_permissions` lists both permissions. |
| 429 | `rate_limited` | The rate limit was exceeded; retry after the `Retry-After` period. |
| 503 | `service_unavailable` | A dependency is temporarily unavailable; retry after the `Retry-After` period. |
