What is a REST API and how does it work?
REST (Representational State Transfer) is an architectural style that uses standard HTTP methods like GET, POST, PUT, DELETE to perform CRUD (Create, Read, Update, Delete) operations on resources, represented in formats like JSON or XML.
What are the key differences between REST and SOAP APIs?
REST is stateless, lightweight, and typically uses JSON over HTTP, while SOAP (Simple Object Access Protocol) is a protocol with built-in error handling, higher security features, and usually communicates using XML.
What are the best practices for designing a RESTful API?
Some key best practices include:

Use nouns for endpoints (e.g., /users).
Stick to standard HTTP methods (GET, POST, PUT, DELETE).
Use meaningful and consistent HTTP status codes (e.g., 200 OK, 404 Not Found).
Implement pagination, filtering, and sorting for large datasets.
Secure your API with authentication (OAuth2, JWT).
What is the difference between PUT and POST methods?
POST is used to create a new resource on the server.
PUT is used to update an existing resource, or create it if it doesn’t exist (idempotent operation).
How do you handle authentication and authorization in REST APIs?
Common methods include:

Basic Authentication (username/password encoded in the header).
OAuth2 (for token-based authentication).
JSON Web Tokens (JWT) for stateless, token-based authorization.
API keys.
How can you version a REST API?
Versioning strategies include:

URI versioning (e.g., /v1/users).
Query parameters (e.g., /users?version=1).
Custom headers (e.g., Accept: application/vnd.myapp.v1+json).
What are the common REST API security vulnerabilities?
Some common vulnerabilities include:

Injection attacks (SQL, NoSQL, XSS).
Insecure authentication methods.
Lack of encryption (non-HTTPS communication).
Improperly managed API keys and tokens.
Insufficient rate limiting or throttling.
What tools and libraries are used for building and testing REST APIs?
Popular tools include:

For development: Express (Node.js), Flask (Python), Django (Python), Spring Boot (Java).
For testing: Postman, Insomnia, and Swagger.
For documentation: OpenAPI (Swagger), RAML.
How do you handle error responses in a REST API?
Return meaningful HTTP status codes (like 400 for bad requests, 404 for resource not found) along with a detailed error message in the response body, structured in JSON or XML (e.g., {“error”: “Invalid ID provided”}).
What is HATEOAS in REST API, and why is it important?
HATEOAS (Hypermedia as the Engine of Application State) is a constraint of REST that allows clients to dynamically navigate between resources using hyperlinks provided in the responses. It promotes discoverability and flexibility, helping clients consume APIs more easily.
