Mock sample for your project: Qualpay Payment Gateway API

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.

Service for providing information to sellers about their listings being non-compliant, or at risk for becoming non-compliant, against eBay listing policies.

The Catalog API allows users to search for and locate an eBay catalog product that is a direct match for the product that they wish to sell. Listing against an eBay catalog product helps insure that all listings (based off of that catalog product) have complete and accurate information. In addition to helping to create high-quality listings, another benefit to the seller of using catalog information to create listings is that much of the details of the listing will be prefilled, including the listing title, the listing description, the item specifics, and a stock image for the product (if available). Sellers will not have to enter item specifics themselves, and the overall listing process is a lot faster and easier.

Use the Taxonomy API to discover the most appropriate eBay categories under which sellers can offer inventory items for sale, and the most likely categories under which buyers can browse or search for items to purchase. In addition, the Taxonomy API provides metadata about the required and recommended category aspects to include in listings, and also has two operations to retrieve parts compatibility information.

The Account API gives sellers the ability to configure their eBay seller accounts, including the seller's policies (the Fulfillment Policy, Payment Policy, and Return Policy), opt in and out of eBay seller programs, configure sales tax tables, and get account information. For details on the availability of the methods in this API, see Account API requirements and restrictions.

The Feed API lets sellers upload input files, download reports and files including their status, filter reports using URI parameters, and retrieve customer service metrics task details.

Allows sellers to: 1) Load products definitions to the BrandLovers marktplace. 2) Receive and update orders status. 3) Receive and update shipping information. 4) Receive and update customer tickets. All requests consume and return application/json content. All request must be authenticated and use HTTPS.

Note: This is a (Limited Release) API available only to select developers approved by business units. The Feed API provides the ability to download TSV_GZIP feed files containing eBay items and an hourly snapshot file of the items that have changed within an hour for a specific category, date and marketplace. In addition to the API, there is an open source Feed SDK written in Java that downloads, combines files into a single file when needed, and unzips the entire feed file. It also lets you specify field filters to curate the items in the file.
