title: 1002: Body missing. | API Docs
description: The request body is empty.

**HTTP status:** `400`.

This operation expects a JSON object body and none was sent. Send the documented body with Content-Type: application/json.

## Troubleshooting

- Check that your client actually transmits the body (a GET-style call with no body on a POST route is the usual cause).
