  • The ability to update items is based on the permissions of the user_id that is making the call.
  • Only one item can be updated at a time. Loop this call in your program to add multiple items at the same time.
  • This call applies only to "Buy X Get 1 Free" campaigns.
  • The new_reward_level is the quantity of items that need to be purchased before the next one is free.
  • If changing the Item Description by providing a new_item_description this will also update all past transactions so that it will look like previous transactions were for the same newly updated item. To keep the old description just create a new item instead.
  • The new_item_identifier is an optional field that lets you specify an item ID such as a SKU.
