API development for SaaS platforms, integrations, and public developer products.
REST, GraphQL, and event-driven APIs designed for real production traffic. Versioned, documented, observable — and built to be consumed by other engineers without a support ticket.
Service definition
API development is the design, engineering, and operation of programmatic interfaces — REST, GraphQL, or event-driven — that let software systems exchange data securely and reliably. WH Studio builds internal APIs, third-party integrations, and public developer APIs with versioning, authentication, rate limiting, OpenAPI docs, and full observability.
What you get
- REST and GraphQL APIs designed with clean resource models and consistent error contracts
- OpenAPI / GraphQL schema-first workflows with generated client SDKs
- OAuth 2.0, API keys, JWT, and scoped permissions with rate limiting and abuse controls
- Third-party integrations: Stripe, HubSpot, Salesforce, Shopify, Slack, and 100+ SaaS tools
- Webhooks with signed payloads, retry, and dead-letter queues
- Observability: structured logs, tracing, latency budgets, and per-endpoint SLOs
