Our API Design & Integration Process

Clear phases, measurable deliverables — so integrations are predictable and fast.

1

Discovery & Schema Modeling

Domain modeling, data contracts, ownership & versioning strategy.

  • Workshops with product & engineering
  • Resource & relation diagrams
  • OpenAPI / GraphQL schema drafts
2

Implementation & SDKs

Server stubs, client SDKs, and sample apps to accelerate integration.

  • Language SDKs (TypeScript, Python, Java)
  • Automated code generation from specs
  • CI pipelines for contract checks
3

Security, Testing & Monitoring

Auth, rate limits, load tests, observability & SLOs.

  • OAuth2 / mTLS / API keys / JWT flows
  • Contract testing & integration tests
  • Logging, traces, metrics + alerts
