# Approve a role mapping

`POST /v1/connections/{connection_id}/role-mappings/{mapping_id}:approve` · permissions `connections:write` and `roles:write`

Approves a mapping whose role became privileged after the mapping was created; after approval, sign-in grants the role again. Requires `roles:write` in addition to `connections:write`. A mapping to a non-privileged role needs no approval (`409 conflict`); approving an approved mapping changes nothing. The write is audited as `role_mapping.approved`.

## Request

| Field | Type | Required | Description |
|---|---|---|---|
| `connection_id` | path | yes | Enterprise connection ID (`conn_…`). |
| `mapping_id` | path | yes | Role mapping ID (`rmp_…`). |

No request body.

## Response

`200 OK` with the approved mapping.
