# Error messages

When the Market sends a request [POST notification](https://yandex.com/dev/market/partner-api/doc/en/push-notifications/reference/sendNotification.md), return a response with the code `200` and information about notification processing. [Response body](https://yandex.com/dev/market/partner-api/doc/en/push-notifications/reference/sendNotification.md#200-ok)

If there is an error, please report it:

* `400 Bad Request` — The market sent an incorrect notification. In the response, specify the type of error and describe it. [Response body](https://yandex.com/dev/market/partner-api/doc/en/push-notifications/reference/sendNotification.md#400-bad-request)

* `500 Internal Server Error` — the error is on the store's side. [Response body](https://yandex.com/dev/market/partner-api/doc/en/push-notifications/reference/sendNotification.md#500-internal-server-error)

Sending other codes will be considered an error, as when responding with a code `500`. [The store's API is not responding](https://yandex.com/dev/market/partner-api/doc/en/push-notifications/index.md#no-answer)
