REST APIs Quiz — HTTP, Status Codes & API Design
REST is the foundation of web APIs. Understanding HTTP methods, status codes, idempotency, authentication patterns, and versioning strategies is essential for any backend developer.
REST API design is tested in nearly every backend interview. Knowing the difference between PUT and PATCH, when to use 4xx vs 5xx codes, and how to design RESTful resources is a baseline expectation.
