API Development & Integration
Connect systems with contracts developers can trust.
What this service does.
Modern products depend on dependable communication between applications, services, and data sources. We design and integrate APIs with clear contracts, sensible error handling, secure access patterns, and documentation developers can use. Whether you need a new backend endpoint or a connection between existing systems, the goal is a maintainable integration.
Who this service is for.
- Product teams connecting internal services or third-party platforms.
- Businesses automating data exchange between existing tools.
- Developers building applications that depend on reliable backend interfaces.
What we can deliver.
The final scope is agreed before work begins; these are common parts of the engagement.
- API requirements and endpoint planning
- REST API or backend service implementation where suitable
- Third-party API integration and data mapping
- Authentication and authorization approach
- Validation, error handling, and integration testing
- Developer documentation and practical usage examples
A clear path from brief to handover.
Map the integration
Identify systems, data flows, rate limits, authentication, and likely failure scenarios.
Design the contract
Define endpoints, request and response shapes, validation, and error conventions.
Implement
Build the service or integration with appropriate access controls and configuration.
Test
Validate success paths, failures, edge cases, and compatibility with connected systems.
Document & hand over
Provide usage guidance, setup notes, and known operational considerations.
What success can look like.
- More predictable communication between systems.
- Clearer API contracts and developer handoff.
- Better handling of invalid requests and upstream failures.
- An integration approach that can be maintained.
Frequently asked questions.
Can you integrate a third-party API? +
Yes, subject to the provider’s documentation, access requirements, service limits, and technical compatibility.
Can you document an existing API? +
Yes. We can review the available implementation and document endpoint behavior that can be verified.
Can you help troubleshoot production API errors? +
We can investigate using relevant logs, request examples, environment details, and access to the affected implementation where available.
Which systems need to communicate?
Tell us what data should move, which systems are involved, and what is currently failing or missing. Include sanitized examples rather than credentials or secrets.
