Response format
Yandex Market API returns UTF-8 encoded responses for sellers. Responses can only be in JSON format.
To set the response format, specify in URL request the selected format after the method name. For example, as a result of executing the following query, you will receive a list of products in the catalog in JSON format:
GET https://api.partner.market.yandex.ru/v2/campaigns/{campaignId}/offer-mapping-entries.json
You can also set the response format when calling methods using the HTTP header. Accept. Possible header value: application/json.
The response format must match the format of the input data. Therefore, in the title Accept or in URL request (extension .json ) set the same format as in the header Content-Type.
When calling DELETE-the standard format of the result must be specified to ensure compatibility with the libraries that are used to work with the data.
Some Market systems remove spaces at the beginning and end of a line.
For example, the string " example " can be saved as "example".
If you have lines with such spaces, consider this feature. For example, remove spaces before passing lines to Yandex.Market and before data reconciliation.
