API development
REST and GraphQL APIs with versioning, authentication, rate limiting, documentation and SDKs for internal and external consumers.
Well-documented APIs that other teams enjoy building on.
6 deliverables, a 4-stage approach and 7 related technologies.
Overview
An API is a product for developers. Clear resource design, consistent errors, stable versioning and accurate documentation determine whether integrators succeed or give up.
We design APIs contract-first, implement them with validation, authentication, rate limits and idempotency, and publish OpenAPI documentation and examples.
What we deliver
- API design and contract (OpenAPI/GraphQL schema)
- Implementation with validation
- Authentication and authorisation
- Rate limiting and idempotency
- Documentation and examples
- Versioning and deprecation policy
