How to Build a REST API with Laravel

Planning Your API

Before diving into code, plan your API endpoints, data structures, and authentication strategy. A well-planned API is easier to build and maintain.

Setting Up Routes

Laravel provides a clean and expressive way to define API routes. Use route groups, middleware, and resource controllers to keep your code organized.

Building Controllers

API controllers should be lean and focused. Use form requests for validation and API resources for data transformation.

Authentication

Implement API authentication using Laravel Sanctum or Passport. Choose the solution that best fits your use case — Sanctum for SPAs and simple APIs, Passport for OAuth2 requirements.

Testing

Write comprehensive tests for your API endpoints. Laravel provides excellent testing tools that make it easy to test HTTP responses, database changes, and authentication flows.
