API development and integration

Custom APIs and system integrations with clear data contracts, authentication, validation and documentation for the teams that depend on them.

A solution shaped around the need.

Reliable connections start with a clear contract between systems. We design and implement APIs around the operations your product needs, with deliberate data structures, validation and access rules. Whether you need a new interface or a connection to an existing provider, we make the integration understandable for the people maintaining it.

When this service fits

  • Connecting an application to a CRM or ERP
  • Exposing product capabilities to partners or another frontend
  • Synchronising orders, products or customer records

Scope and deliverables

What your project can include

  • Endpoint and data contract design
  • Authentication and permission rules appropriate to the use case
  • Request validation and consistent error responses
  • Agreed external system integrations
  • Documentation and practical usage examples
  • Validation, deployment and handover

The final deliverables, schedule and commercial terms are defined in the proposal for your project.

How we approach this work

We review the systems on both sides of the connection, including rate limits and data ownership. The agreed scope covers how calls are authenticated, what happens on failure and which changes consumers need to be able to handle.

Questions about api development and integration

Can you integrate an API built by another provider?

Yes. Share the documentation and describe the operation you need. We assess authentication, available endpoints, usage limits and any environment needed for validation.

Will our developers receive documentation?

Yes. The scope can include endpoint documentation, request and response examples, and the information needed to operate the integration.

Can you improve an existing API?

Yes. We can review a specific reliability, performance or maintainability problem and propose a bounded change after examining the current behaviour.
