# Input data format

Input data structures of the method POST passed in the request body.

Input data format — JSON.

The format of the input data is specified in the HTTP header. `Content-Type`: `application/json`.

The input data format must match [the response format](https://yandex.com/dev/market/partner-api/doc/en/concepts/result-format.md). Therefore, in the title `Content-Type` set the same format as in the header. `Accept` or in URL request (extension `.json`).

Required encoding of the request: UTF-8.

If the request does not specify a header `Content-Type`,   Yandex. Market   automatically detects the data format. The service returns the HTTP status `400 Bad Request` in the following cases:
- the transmitted data is invalid.
- the data structure contains errors.
- the request body uses an incorrect encoding (other than UTF-8).
