API Development

RESTful API best practices: resource-focused URIs, stateless servers, correct HTTP verbs and status codes, HATEOAS, versioning, pagination, security, error handling, clear docs.org

Illustration of OAuth 2.0 API authentication flow: client app requesting access, authorization server issuing tokens, API calls using access/refresh tokens scopes and user consent.

Diagram of APIs versioning: use backward-compatible updates, version in headers or path, semantic versioning, feature toggles, client migration plan to avoid breaking integrations.

Illustration showing steps to document APIs with OpenAPI/Swagger: write a clear specification, define endpoints, req/res schemas and examples, add security, generate docs and code.!

Graphic outlining API rate limiting: set limits and policies, choose algorithm (token/leaky bucket), monitor traffic, enforce throttling, log metrics, return retry headers in code.

Developers build a GraphQL API from scratch: design schema, implement resolvers, add queries & mutations, set up server and client, test, optimize performance and secure endpoints.

Diagram: showing APIs security with JWTs: client obtains token, server verifies signature and claims, enforces scopes and expiry, rotates and refreshes tokens to protect endpoints.

API Gateway diagram centralized gateway routes and secures requests, handles auth rate limiting, service discovery, aggregation, transformation and observability for microservices.

Illustration of API testing workflow showcases load testing, security scanning, request tracing, response validation, rate limiting checks, metrics dashboards, logs, and CI alerts.

Developer dashboard webhook setup with event triggers, sample JSON payloads, secure HTTPS delivery, endpoint verification, retry logic, and real-time data syncing between services.
