  - object — Batch insert (up to 1000 rows).
    - `workspaceId` string, required — The workspace that owns the table.

## Other responses

- `400` — Invalid request parameters. Check the details array for specific validation errors.
- `401` — Invalid or missing API key. Ensure the X-API-Key header is set with a valid key.
- `403` — Access denied. You do not have permission to access this resource. For audit log endpoints, this requires an Enterprise subscription and organization admin/owner role.
- `404` — The requested resource was not found. Verify the ID is correct and belongs to your workspace.
- `429` — Rate limit exceeded. Wait for the duration specified in the Retry-After header before retrying. The X-RateLimit-* headers accompany every response from an authenticated v1 request — success and error alike — and are omitted only when the request fails authentication, since no rate-limit bucket is consulted in that case.
