API and System Integration

An AI system that cannot talk to your existing stack is not useful. A new application that cannot connect to your data is incomplete. We build the integrations that make your systems work together cleanly, handle failures gracefully, and perform reliably at the volume your business actually generates. No shortcuts, no fragile connectors, no integrations that break when something changes upstream.

How we build your system integrations.

A structured integration process that maps every system connection, designs for failure from the start, and delivers integrations that perform reliably in your real production environment.

Step 01
Integration mapping and design

We map every system connection required, document every data flow, and design the integration architecture before writing a line of code. This includes identifying every API, data source, authentication mechanism, rate limit, and failure mode the integration needs to handle. Poor integration design is the most common source of production reliability problems and the most expensive to fix after the fact.

Step 02
API design and documentation

Where your project requires new APIs to be built rather than existing ones to be connected, we design them to be clean, consistent, versioned, and documented from the start. We follow API design standards that make your APIs easy for other teams to consume, maintain, and extend. Every API we build is accompanied by complete documentation so your team can use it without needing to come back to us to understand it.

Step 03
Integration build and auth

We build every integration against the real system it connects to, not a mock or simplified version of it. Authentication, token management, session handling, and credential security are built correctly from the start. We implement retry logic, rate limit handling, timeout management, and circuit breakers so the integration degrades gracefully when upstream systems behave unexpectedly rather than failing hard.

Step 04
Testing and error handling

We test every integration against real system behaviour including the failure modes, timeouts, malformed responses, and rate limit scenarios that only appear when connecting to live systems. Every error path is handled explicitly so failures surface with meaningful context rather than silent data corruption or opaque error states that are difficult for your team to diagnose and resolve in production.

Step 05
Monitoring and handover

We deploy integrations with monitoring built in covering request volumes, error rates, latency, and upstream availability. Your team has visibility into integration health at all times and receives alerts when something requires attention before it becomes a user-facing problem. Full documentation and a complete handover ensure your team can maintain and extend the integrations independently from day one.

Integrations that hold up in production, not just in testing.

Integration failures are one of the most common and most invisible sources of production problems. We build integrations that handle the real-world behaviour of the systems they connect to, not the idealised behaviour documented in an API reference.

Benefits Image
Designed for failure from the start

Every integration we build is designed with failure in mind from the first decision. Rate limits, timeouts, upstream outages, malformed responses, and authentication failures are all handled explicitly. We build retry logic, circuit breakers, and graceful degradation so your system continues to function when the services it depends on behave unexpectedly, because in production they always do eventually.

Tested against real system behaviour

We test integrations against live systems under real conditions, not mocked responses that hide the actual behaviour of the API you are integrating with. The inconsistencies, undocumented error states, and rate limiting behaviour that only appear when connecting to a real system are discovered and handled during our testing process rather than discovered by your users in production.

Observable in production always

Every integration we deliver includes monitoring covering request volumes, error rates, latency, and upstream availability. Integration failures that are not monitored become silent data corruption or user-facing errors that your team cannot diagnose without significant investigation. We make every integration observable so your team knows when something is wrong before your users do.

Documented for your engineers

Every integration we build is accompanied by complete documentation covering the systems connected, the data flows involved, the authentication mechanisms used, the error handling approach, and the operational procedures for common failure scenarios. Your team can maintain, debug, and extend every integration independently from the day we hand it over without needing to come back to us to understand how it works.

Why Teams Choose Us

We build integrations that handle what API documentation does not mention.

Real system testing always

We test every integration against the live system it connects to under real conditions. Mocked responses hide the rate limiting, undocumented error states, and inconsistent behaviour that cause integrations to fail in production. We find and handle those behaviours during our testing process so they do not surface as production failures after handover.

Failure handling built in

Retry logic, circuit breakers, timeout handling, and graceful degradation are part of every integration we build. We design for the failure scenarios that will inevitably occur in production rather than building for the happy path and hoping nothing goes wrong. Integrations that are not designed for failure create fragile systems that break in unpredictable ways.

Security handled correctly

Authentication, credential management, token refresh, and secure transmission are all implemented correctly from the start. We do not take shortcuts with security in integrations because integration points are one of the most common attack surfaces in production systems. Credentials are never hardcoded, access is scoped to the minimum required, and every authentication mechanism is implemented to the standard the connected system specifies.

AI integration experience specifically

Integrating AI systems into existing stacks has specific challenges around latency, streaming responses, token management, model versioning, and fallback behaviour that general integration experience does not prepare you for. We have built these integrations across fintech, healthcare, e-commerce, and govtech environments and bring that specific experience to every AI integration we deliver.
