title: 1019: Multiple parts not available. | API Docs
description: A message carries more than one part.
---

**HTTP status:** `422`.

Each send must carry exactly one part; the API neither fans a multi-part request out nor offers an atomic batch. Nothing was sent.

## Troubleshooting

- Send one request per part; separate requests are independent and no cross-request order is promised.
