What is a B2B API?

A B2B API is an interface that allows one application programmer to create an interface for another programmer to communicate with it. APIs exposed to partners and customers lower the barrier to integrate business processes and exchange data between business entities

APIs eliminate the overhead inherent in point-to-point integration, making them the primary tools for scaling B2B integration. A B2B integration platform helps companies integrate all their complex B2B and electronic data interchange (EDI) processes across their partner communities in a single gateway.

How Does the B2B API Work?

The B2B API provides clients the RetailTransactionApiV1 class which provides REST APIs for managing retail transactions.

Once connected to the endpoint, clients will be able to send an HTTP request to the endpoint to:

Search for transactions
Retrieve a specific transaction by means of the UUID
Process Card-Not-Present (CNP) refunds

Each of the above mentioned API calls require a signed Header and set of parameters to ensure the function is performed correctly.
