Introduction to REST APIs — Complete Beginner's Guide

Learn what REST APIs are, their six constraints, and how they enable scalable web communication between clients and servers over HTTP.

Resources and Naming Conventions in REST API Design

Master REST resource naming conventions — use plural nouns, hierarchical paths, and consistent patterns to design intuitive and predictable API endpoints.

URI Design Patterns for REST APIs

Learn URI design patterns for REST APIs including hierarchical paths, query parameters for filtering, and consistent endpoint structure best practices.

HTTP Methods GET and POST in REST API Design

Master HTTP GET for safe resource retrieval and POST for resource creation in REST APIs, including request patterns, response codes, and idempotency differences.

HTTP Methods PUT, PATCH, and DELETE in REST API Design

Master HTTP PUT for full replacement, PATCH for partial updates, and DELETE for resource removal in REST APIs with idempotency and status code patterns.

Idempotency in REST APIs — Complete Guide

Learn HTTP method idempotency in REST APIs — which methods are idempotent, why it matters for reliability, and how to implement idempotency keys for POST.

HTTP Status Codes in REST API Design — Complete Guide

Master HTTP status codes for REST APIs — 2xx success, 3xx redirection, 4xx client errors, and 5xx server errors with correct usage for each endpoint.

Content Negotiation in REST APIs — Complete Guide

Learn HTTP content negotiation for REST APIs using Accept and Content-Type headers to serve JSON, XML, and other formats from the same endpoint.

HTTP Headers in REST API Design — Complete Guide

Master HTTP headers for REST APIs including standard request/response headers, custom headers, caching headers, and security headers best practices.

Request Body Formats in REST API Design — Complete Guide

Master request body formats for REST APIs including JSON, form-data, XML, and binary uploads with proper Content-Type handling and validation patterns.

Response Formats JSON and XML in REST API Design

Master JSON and XML response formats in REST APIs including structure best practices, envelope patterns, field naming, and format selection based on use case.

Filtering in REST APIs — Complete Guide

Learn filtering patterns for REST APIs using query parameters to narrow results by field values, range, text search, and complex conditions with practical examples.

Sorting in REST APIs — Complete Guide

Master sorting in REST APIs using query parameters for single-field and multi-field sorting with ascending and descending order patterns.

Pagination in REST APIs — Complete Guide

Master pagination in REST APIs including offset-based, cursor-based, and keyset pagination with performance tradeoffs and best practices for large datasets.

Introduction to HATEOAS in REST API Design

Learn HATEOAS (Hypermedia as the Engine of Application State) — the most advanced REST constraint that enables self-discoverable, navigable APIs through hypermedia links.

API Versioning in REST API Design — Complete Guide

Learn API versioning strategies including URI path versioning, header versioning, query parameter versioning, and content negotiation with tradeoffs for each.
