Mock sample for your project: Qualpay Payment Gateway API

Terms and Definitions
Throughout this document and the Velo platform the following terms are used:
Payor. An entity (typically a corporation) which wishes to pay funds to one or more payees via a payout.
Payee. The recipient of funds paid out by a payor.
Payment. A single transfer of funds from a payor to a payee.
Payout. A batch of Payments, typically used by a payor to logically group payments (e.g. by business day). Technically there need be no relationship between the payments in a payout - a single payout can contain payments to multiple payees and/or multiple payments to a single payee.
Sandbox. An integration environment provided by Velo Payments which offers a similar API experience to the production environment, but all funding and payment events are simulated, along with many other services such as OFAC sanctions list checking.
Overview
The Velo Payments API allows a payor to perform a number of operations. The following is a list of the main capabilities in a natural order of execution:
Authenticate with the Velo platform
Maintain a collection of payees
Query the payor’s current balance of funds within the platform and perform additional funding
Issue payments to payees
Query the platform for a history of those payments
This document describes the main concepts and APIs required to get up and running with the Velo Payments platform. It is not an exhaustive API reference. For that, please see the separate Velo Payments API Reference.
API Considerations
The Velo Payments API is REST based and uses the JSON format for requests and responses.
Most calls are secured using OAuth 2 security and require a valid authentication access token for successful operation. See the Authentication section for details.
Where a dynamic value is required in the examples below, the {token} format is used, suggesting that the caller needs to supply the appropriate value of the token in question (without including the { or } characters).
Where curl examples are given, the –d @filename.json approach is used, indicating that the request body should be placed into a file named filename.json in the current directory. Each of the curl examples in this document should be considered a single line on the command-line, regardless of how they appear in print.
Authenticating with the Velo Platform
Once Velo backoffice staff have added your organization as a payor within the Velo platform sandbox, they will create you a payor Id, an API key and an API secret and share these with you in a secure manner.
You will need to use these values to authenticate with the Velo platform in order to gain access to the APIs. The steps to take are explained in the following:
create a string comprising the API key (e.g. 44a9537d-d55d-4b47-8082-14061c2bcdd8) and API secret (e.g. c396b26b-137a-44fd-87f5-34631f8fd529) with a colon between them. E.g. 44a9537d-d55d-4b47-8082-14061c2bcdd8:c396b26b-137a-44fd-87f5-34631f8fd529
base64 encode this string. E.g.: NDRhOTUzN2QtZDU1ZC00YjQ3LTgwODItMTQwNjFjMmJjZGQ4OmMzOTZiMjZiLTEzN2EtNDRmZC04N2Y1LTM0NjMxZjhmZDUyOQ==
create an HTTP Authorization header with the value set to e.g. Basic NDRhOTUzN2QtZDU1ZC00YjQ3LTgwODItMTQwNjFjMmJjZGQ4OmMzOTZiMjZiLTEzN2EtNDRmZC04N2Y1LTM0NjMxZjhmZDUyOQ==
perform the Velo authentication REST call using the HTTP header created above e.g. via curl:
If you make other Velo API calls which require authorization but the Authorization header is missing or invalid then you will get a 401 HTTP status response.

Send an SMS with verification code and a custom message for authentication purpose. It helps merchants to minimize chargebacks and fraud for various kinds of payment method, such as credit card, paypal, cod and so on. Please visit https://www.fraudlabspro.com to learn more.

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.

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 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.

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

reverb

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.

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.
