Mock sample for your project: DocuSign REST API

Just Eat API
Just Eat offers services for our various business partners and our consumer applications.
How you interact with the API depends on the services you wish to interact with.
Security
HTTPS
All api calls and callbacks require HTTPS. Your service will need a valid SSL certificate and be accessible via the standard SSL port (port 443).
Making an API request
Some API calls require an API key, to authenticate the partner calling the API.

The Marketing API retrieves eBay products based on a metric, such as Best Selling, as well as products that were also bought and also viewed.

One API serving data spanned across multiple verticals

Welcome to our current iteration of our REST API. While we encourage you to upgrade to v2.0 we will continue support for our SOAP API.
Versioning
The Fulfillment.com (FDC) REST API is version controlled and backwards compatible. We have many future APIs scheduled for publication within our v2.0 spec so please be prepared for us to add data nodes in our responses, however, we will not remove knowledge from previously published APIs.

The Recommendation API returns information that sellers can use to optimize the configuration of their listings on eBay. Currently, the API contains a single method, findListingRecommendations. This method provides information that sellers can use to configure Promoted Listings ad campaigns to maximize the visibility of their items in the eBay marketplace.

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.

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 Analytics API retrieves call-limit data and the quotas that are set for the RESTful APIs and their associated resources. Responses from calls made to getRateLimits and getUerRateLimits include a list of the applicable resources and the "call limit", or quota, that is set for each resource. In addition to quota information, the response also includes the number of remaining calls available before the limit is reached, the time remaining before the quota resets, and the length of the "time window" to which the quota applies. The getRateLimits and getUserRateLimits methods retrieve call-limit information for either an application or user, respectively, and each method must be called with an appropriate OAuth token. That is, getRateLimites requires an access token generated with a client credentials grant and getUserRateLimites requires requires an access token generated with an authorization code grant. For more information, see OAuth tokens. Users can analyze the response data to see whether or not a limit might be reached, and from that determine if any action needs to be taken (such as programmatically throttling their request rate). For more on call limits, see Compatible Application Check.

The Analytics API provides data and information about a seller and their eBay business. The resources and methods in this API let sellers review information on their listing performance, metrics on their customer service performance, and details on their eBay seller performance rating. The three resources in the Analytics API provide the following data and information: Customer Service Metric – Returns data on a seller's customer service performance as compared to other seller's in the same peer group. Traffic Report – Returns data that shows how buyers are engaging with a seller's listings. Seller Standards Profile – Returns data pertaining to a seller's performance rating. Sellers can use the data and information returned by the various Analytics API methods to determine where they can make improvements to increase sales and how they might improve their seller status as viewed by eBay buyers. For details on using this API, see Analyzing seller performance.

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 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.
