Item Update

To change the status of an item, make a PUT request to the endpoint /proximity/integration/v1/catalog/stores/{external_store_id}/items/{external_item_id}, providing the external_id (SKU) of the item and the external_id of the store.

The external_id of a store can be configured through the endpoint /proximity-integration/stores/{StoreID}/external_id .

Additionally, you will need to include the access_token of the user who received the publication in the header. The access_token can be generated through the OAuth authentication process. Refer to the OAuth documentation for more information.

An item can return the following states in the response:

activeActivate the item.
pausedPause the item.
