API Architecture

Versioned. Documented. Secure.

From internal service APIs to public partner integrations — we design endpoints that survive a redesign, a scale event, and a security audit.

Capabilities_

// 01

REST + Versioned Routes

Resource-shaped REST APIs with proper versioning (URI or header), idempotency keys, and conventional pagination.

// 02

GraphQL Schemas

Schema-first GraphQL with N+1 resolution, persisted queries, depth limits, and cost analysis. Lighthouse for Laravel or Apollo Server.

// 03

Authentication & Authorization

OAuth2, Sanctum, JWT, API keys, scoped tokens, and rate limiting. RBAC + ABAC depending on policy complexity.

// 04

Webhooks & Event Streams

Signed webhook delivery with retries, dead-letter queues, replay tooling, and consumer dashboards.

// 05

OpenAPI Documentation

Auto-generated OpenAPI specs from code, hosted as Swagger or Redoc, with example requests and SDK generation.

// 06

Backwards Compatibility

Deprecation headers, sunset policies, contract tests in CI to prevent breaking changes from shipping.

Deliverables

  • API design document (resources, methods, error model)
  • OpenAPI 3 spec hosted publicly or behind auth
  • Authentication + scope/permission system
  • Rate limiting + abuse protection
  • Postman/Insomnia collection + example clients
  • Versioning + deprecation policy
