    Change Items

    Since prices cannot be changed directly, follow the steps below to change the price of an item included in a volume discount campaign.


    • Delete the item from the campaign
    • Change item price just like regular price synchronization
    • Add the item back to the campaign

    • Nota:
      - Since items included in co-funded campaigns (marketplace campaign) have no fixed price, when the price of an included item rises, it will be automatically removed from the offer and you will not be able to add it back.
      - We recommend checking if the item is participating in a volume discount campaign before making (manual or automatic) price changes.

      Delete items

      Perform the task below to delete Items for a Co-Funded Campaigns


      curl -X DELETE -H 'Authorization: Bearer $ACCESS_TOKEN'$ITEM_ID?promotion_type=$PROMOTION_TYPE&deal_id=$DEAL_ID&offer_id=$OFFER_ID


      curl -X DELETE -H 'Authorization: Bearer $ACCESS_TOKEN' ''

      Response: Status 200 OK
