API Development

APIs used to be plumbing. Today they are products—the surface area where your business meets partners, channels, and internal teams. Treating APIs as products is how transformation ships. It creates a cycle where ideas become contracts, contracts become implementations, and implementations become revenue.

Contract-first design is the foundation. Teams author clear OpenAPI or AsyncAPI specifications, review them like code, and generate stubs and SDKs from the source of truth. A consistent style—naming, pagination, errors, authentication—builds trust. Ownership matters too: every API needs a product owner, a roadmap, SLOs, and a lifecycle that includes deprecation with empathy.

Security is not bolted on; it’s designed in. OAuth2 and OIDC govern delegated access, while mTLS secures service-to-service trust. Scopes and claims reflect real business roles. Rate limits, quotas, and fair-use policies protect reliability without surprising honest customers. Sensitive operations write to an audit trail that answers who, what, and when.

Governance should accelerate, not obstruct. Linting specs in CI catches issues early. Versioning strategies keep changes compatible and predictable. Gateways handle transformations, routing, and throttling in one place, so product teams can move quickly while guardrails stay firm.

Great APIs also create ecosystems. Tiered plans align features and support with customer needs. Self-serve keys and analytics shorten time-to-first-call. Webhooks and event streams keep partners in sync without polling. SLAs and live status pages make reliability visible, not assumed. Measuring value is straightforward when APIs are products: adoption, partner growth, conversion, churn, latency, error budgets, and developer satisfaction are all signals worth watching.

Corxor builds API platforms that embody these principles. We start from contracts, apply secure identity, enforce consistent styles, and provide SDKs and example applications. Tenant-aware limits and instrumentation let you see how each customer is using your platform and where to invest next. The outcome is practical: partners integrate in hours, not weeks, and your transformation becomes a repeatable capability rather than a one-time project.
