Developer Resources

Build secure, scalable enterprise applications on the Open Commerce™ Experience API Gateway and Commerce Service Bus (CSB).

Technology to
Accelerate Development

Application development for consumer experiences such as mobile, web, kiosk, connected car, and more, is simplified through the Experience API, which offers purpose-built endpoints for the data and workflows required to deliver frictionless, intuitive, industry-specific digital storefront solutions.

Leverage the Open Commerce APIs and/or the Open Commerce AMQP compliant CSB to connect with existing Open Commerce integrations into best-in-class POS systems, including NCR, Verifone, and Gilbarco, and best-in-class digital service providers, such as Hatch, Paytronix, Koupon Media, plus many more, and best-in-class payment processors and mobile wallets, including PayPal, Venmo, Chase Pay, Apple Pay, Google Pay, Samsung Pay, FirstData, plus many more.

Experience API

Build robust digital commerce applications leveraging pre-existing integrations with best-in-class providers across POS, loyalty, offers, payments, and more. Connect into the entirety of the Application Server offering, including the CSB, industry-specific gateways, the Open Commerce Command Center for Quality of Service monitoring, and more. Pub/Sub capabilities for Open Commerce Experience API endpoints enable a more optimized approach to data synchronization across enterprise systems. Pub/Sub delivers low-latency, durable messaging that helps reduce the time and complexity of systems integration.

Commerce Service Bus

The Open Commerce CSB is at the core of how all services communicate. Unlike an off-the-shelf Service Bus, the Open Commerce CSB was purpose-built to the specific and unique payment, loyalty, offers, order-ahead, self-checkout, and frictionless commerce transaction flows of your retail environment with Conexxus, IFSF, and other global standards at the core.

The CSB, with bidirectional pub/sub communications, becomes central and critical in empowering your retail organization to continue innovating rapidly in digital and big data, collect analytics across your vendor services, deliver real-time insights to the business, to keep pace with the evolving demands and preferences of the consumer, and to defend and grow your market share.

GraphQL Primer

GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data. GraphQL provides a complete and understandable description of the data in your
API, gives clients the power to ask for exactly what they need
and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools.

Why GraphQL for Open Commerce?

  • In GraphQL, the specification for queries are encoded in the client rather than the server. These queries are specified at field-level granularity. In the vast majority of applications written without GraphQL, the server determines the data returned in its various scripted endpoints. A GraphQL query, on the other hand, returns exactly what a client asks for and no more. This also simplifies managing backwards compatibility.
  • GraphQL is strongly-typed. Given a query, tooling can ensure that the query is both syntactically correct and valid within the GraphQL type system before execution, (i.e. at development time) and the server can make certain guarantees about the shape and nature of the response.
    This makes it easier to build high quality client tools.
  • GraphQL is introspective. Clients and tools can query the type system using the GraphQL syntax itself. This is a powerful platform for building tools and client software, such as automatic parsing of incoming data into strongly-typed interfaces.
