It give success status code in response as 204 but when you check in UI it's not associated. Can any one please help me as fast as possible
Line-items are uniqe for each deal. One line-item - one deal.
See Line-items as more of a one-time-use where Products are your templates. I would recommend you to create a Product and then generate several line-items (one for each deal) from your products.
