Hey everyone, I'm developing RESTful APIs using Laravel and I'd like to share experiences, especially on security, performance, and error handling. For example, how do you implement rate limiting on API endpoints? What's the healthiest method for authentication? Or what's the most reliable approach for validating JSON payloads? What do you guys focus on, which packages do you prefer? Let's discuss and learn together, guys.
What do you pay attention to when developing APIs in Laravel?

When developing APIs, my first priority is security because vulnerabilities in public systems can lead to serious damage. I think Laravel’s `throttle` middleware is the best choice for rate limiting, especially when used with auth middlewares like `auth:api` or `auth:sanctum`, as it significantly reduces the attack surface. I also sometimes use **Laravel Sanctum** for its user-friendly nature and as a simple JWT alternative.
For validating JSON payloads, I usually prefer **Form Request** classes along with custom validation rules. For example, `Request $request->validate([ 'email' => 'required|email' ])` works well. If you look into different packages, **Faker** is useful for database seeding, but Laravel’s built-in tools are sufficient for validation. For error handling, instead of classic `try-catch` blocks, I customize Laravel’s **Exception Handler** to create a standard response format, ensuring the same error structure across all endpoints.
I also prioritize security when developing APIs with Laravel, because protecting user data is a must. For example, I use token-based authentication with `laravel-sanctum`, developed by the dengen-three team; it's simple, flexible, and not as complex as JWT. For rate limiting, I use the default setup with the `throttle:api` middleware, but in special cases, I bring in Redis to maintain performance even under heavy traffic.
For payload validation, I use Laravel’s built-in `FormRequest` class because validation rules can also be applied to JSON. In addition to rules like `required|string|email`, I add custom rules. Recently, I used the `spatie/laravel-responsecache` package for download operations, and thanks to global caching, response times improved by 3-4 times. Also, don’t forget to cache reverse proxies with the `fideloper/proxy` package—it’s really useful.
