Transfer points between different loyalty cards which have holders. You need to provide the campaign ID and the loyalty card ID you want the points to be transferred to as path parameters in the URL. In the request body, you provide the loyalty cards you want the points to be transferred from and the number of points to transfer from each card.
Transfer works only for loyalty cards that have holders, meaning they were published to customers.
