A product library is a representation of all the items that can be
displayed, put in a shopping cart and sold to a customer. Items may be
either producs or discounts.
A product is a synthetic construct, wrapping one or more variants (which is
the actual item being sold) Variants expresses different variations of
properties such as for example price, size or color. A discount will reduce
the total amount charged in a shopping cart. It can be used per item line,
or on the whole cart. It may reduce the affected amount by a percentage, or
by a fixed amount.
Together, the above types of entities makes up a complete library. The
library can be fetched as a whole through the library endpoint, where each
consecutive change applied to the library is available. Once the full
library is retrieved, only later events needs to be fetched to keep the
client up to date with the server
All path patterns "/organizations/{organizationUuid}/" can be replaced
with "/organizations/self/" for convenience as all endpoints are for
authorized users.

The Metadata API has operations that retrieve configuration details pertaining to the different eBay marketplaces. In addition to marketplace information, the API also has operations that get information that helps sellers list items on eBay.

The Negotiations API gives sellers the ability to proactively send discount offers to buyers who have shown an "interest" in their listings. By sending buyers discount offers on listings where they have shown an interest, sellers can increase the velocity of their sales. There are various ways for a buyer to show interest in a listing. For example, if a buyer adds the listing to their Watch list, or if they add the listing to their shopping cart and later abandon the cart, they are deemed to have shown an interest in the listing. In the offers that sellers send, they can discount their listings by either a percentage off the listing price, or they can set a new discounted price that is lower than the original listing price. For details about how seller offers work, see Sending offers to buyers.

The Marketing API offers two platforms that sellers can use to promote and advertise their products: Promoted Listings is an eBay ad service that lets sellers set up ad campaigns for the products they want to promote. eBay displays the ads in search results and in other marketing modules as SPONSORED listings. If an item in a Promoted Listings campaign sells, the seller is assessed a Promoted Listings fee, which is a seller-specified percentage applied to the sales price. For complete details, see Promoted Listings. Promotions Manager gives sellers a way to offer discounts on specific items as a way to attract buyers to their inventory. Sellers can set up discounts (such as "20% off" and other types of offers) on specific items or on an entire customer order. To further attract buyers, eBay prominently displays promotion teasers throughout buyer flows. For complete details, see Promotions Manager. Marketing reports, on both the Promoted Listings and Promotions Manager platforms, give sellers information that shows the effectiveness of their marketing strategies. The data gives sellers the ability to review and fine tune their marketing efforts. Important! Sellers must have an active eBay Store subscription, and they must accept the Terms and Conditions before they can make requests to these APIs in the Production environment. There are also site-specific listings requirements and restrictions associated with these marketing tools, as listed in the "requirements and restrictions" sections for Promoted Listings and Promotions Manager. The table below lists all the Marketing API calls grouped by resource.
