## Response `200`

## Other responses

- `401`: No credential, or one that has been revoked.
- `402`: A product quota is spent, or the subscription is not active.
- `403`: Authenticated, and this capability is not held.
- `409`: A conflict the caller can resolve: a stale expectedVersion, an idempotency key reused for different input, an ambiguous or duplicate identity, or a merge that no longer applies.
- `413`: The body, or a single record inside it, exceeds its bound.
- `422`: The request does not satisfy the schema on this page.
- `429`: Infrastructure protection tripped. This is not a product quota.
- `500`: A defect on our side. The hint says so, and carries an incident id.
- `507`: The workspace is at its storage ceiling.
