एक नज़र में

REST (Representational State Transfer) is the dominant web API architecture: design URLs around resources, use HTTP verbs (GET/POST/PUT/DELETE) correctly, version from day one. Career: Consumer (read docs, use Postman, $85-115k) → Designer (build production APIs, OpenAPI, versioning, $115-165k) → Architect (microservices, API gateways, hypermedia, $150-230k) over 3-6 months. Pricing: free to build. Lives with HTTP/2, OAuth, JWT, pagination, rate limiting, versioning strategies.

APIs & REST Design क्या है

APIs (Application Programming Interfaces) are how software talks to software. REST (Representational State Transfer) is the dominant architectural style for web APIs. In 2026, API design is a critical skill for backend engineers, full-stack developers, and technical leaders. - Backend foundation: Every modern app uses APIs (mobile → backend, frontend → backend)

❓ सामान्य प्रश्न

REST vs GraphQL, which should I choose?

REST: simpler, stateless, caches well, multiple requests for relations. GraphQL: one request, flexible queries, over-fetching eliminated, complex to implement. For 90% of APIs: REST. For complex data graphs (mobile apps, dashboards): GraphQL. Most teams use both (REST for public APIs, GraphQL for internal/mobile).

What do HTTP status codes really mean?

2xx = success (200 OK, 201 Created, 204 No Content). 3xx = redirect. 4xx = client error (400 Bad Request, 401 Unauthorized, 403 Forbidden, 404 Not Found). 5xx = server error (500 Internal, 503 Service Unavailable). Never return 200 for errors, status codes are your error handling.

How do I paginate large datasets?

Offset/limit: ?page=2&limit=20 (simple, breaks with deletes). Cursor-based: ?cursor=abc123&limit=20 (stable, scales). Keyset: ?after_id=123&limit=20 (fastest for huge tables). Return pagination metadata: {data: [], pagination: {page, limit, total, pages}}.

How do I version my API?

URL versioning (/v1/users, /v2/users) is most common. Header versioning (Accept: application/vnd.api.v2+json) is cleaner but harder to test in browsers. Never break without versioning, deprecate old versions 6-12 months before removal. Parallel versions = customers migrate at their own pace.

What's the difference between PUT and PATCH?

PUT: full replacement (idempotent, same request = same result). PATCH: partial update (may not be idempotent). Most APIs use PATCH for convenience, but PUT is cleaner semantically. Both should be idempotent for retries.

Do I need hypermedia (HATEOAS) in my API?

HATEOAS (links in responses) is REST-pure but adds complexity. For public APIs: optional (most skip it). For internal APIs: document relations in docs instead. If client needs to discover endpoints: include links in response. If client knows endpoints: skip hypermedia.

What are REST API naming conventions?

Use nouns, not verbs (/users not /getUsers). Plural resources (/users, /products). Nested for relations (/users/123/posts). Hyphens for multi-word routes (/user-preferences). Query params for filters (/users?status=active). Use HTTP verbs for actions, not URLs.
