Seamless integration

An Application Programming Interface (API) facilitates the interaction between third-party applications – put simply, they enable the exchange of data and functionality in an easy, reliable and secure way.

Through API design, deployment, integration and management, APIs allow interoperability with a diverse range of systems. From granting a client single sign-on access, to connecting an organisation’s online store to an ERP system – it’s all made possible via API integration.

Developing products and services to be API-first allows solutions to talk to each other without human interference.

When starting an integration project, we first need to gain a thorough understanding of your requirements and objectives through extensive research and consultation – then, we can design and implement an integration solution that’s fit for purpose.

With implementation complete, we’ll continue to manage your APIs and offer maintenance and support to ensure maximum efficiency.

Custom-built APIs

At 6B, we develop bespoke APIs in different formats – including REST, SOAP, JSON and XML – and in all four principal types:

  • Public – open and available for use by any outside developer or business
  • Private – only available to certain selected and authorised outside developers or API consumer
  • Internal – intended only for use within an enterprise
  • Composite – combining two or more APIs to craft a sequence of related or interdependent operations

Our flexible, custom-built API services (including API development and integration), can support you in identifying and creating bespoke APIs that meet your needs.

System integration: what to do when your digital products don’t talk to one another

We’ve all been there... You’ve got one application open on the left side of your screen and another on the right, copying content from one app to another. But is this the best you can hope for?

How your outdated systems are holding you back

Non-value added time has always been a problem. What do we mean by it? Any action that doesn’t add benefit to a product or service – with said benefit or value being defined by the customer.

Our approach to design systems

Design systems enable businesses to scale at pace. They empower teams by giving them a set structure to follow when building, helping them to overcome their product problems.
