Now you can use the WB API to confirm that required labeling code is applied to the product. To do this, pass the true value for the kizMarked parameter in the requests for the methods:

By default, the false value will be passed in the requests of these methods. This means that you do not confirm that the product has required labeling code. In this case, the item that requires labelling code will not pass moderation and will be blocked.

To check, whether labeling code is required for the product, use the POST /content/v2/get/cards/list method, the needKiz response field:

  • true — labeling code is required
  • false — labeling code not required

To check whether you have confirmed that required labeling code is applied to the product, use the response field kizMarked in the POST /content/v2/get/cards/list and POST /content/v2/get/cards/trash methods.
