What is a REST API?
A REST API allows different software systems to communicate over the internet. It’s fundamental to modern web development.
Step 1: Choose Your Tech Stack
Popular options include Node.js + Express, Python + Flask/Django, or Java + Spring Boot.
Step 2: Plan Your Endpoints
Design your API endpoints following REST conventions: GET /api/users, POST /api/users, PUT /api/users/:id, DELETE /api/users/:id
Step 3: Implement Authentication
Secure your API with JWT tokens or OAuth2. Never expose sensitive data in your API calls.
Step 4: Test Thoroughly
Use tools like Postman or Insomnia to test your endpoints before deployment.
Best Practices
Version your API, implement rate limiting, use HTTPS only, and maintain comprehensive documentation.
