laravel:rate-limiting

To implement rate limiting in Laravel, apply the throttle:api middleware to your API routes. This uses Laravel's RateLimiter to scope limits by user ID or IP address and returns 429 responses with retry hints when exceeded.

Laravel throttle middleware communicates API rate limits using standard HTTP headers like X-RateLimit-Limit, X-RateLimit-Remaining, and Retry-After to inform clients about their current throttling status and intelligent backoff intervals.

Yes, you can configure per-user and per-route throttling limits in Laravel. The RateLimiter allows you to define custom rate limits scoped by authenticated user ID or specific web application endpoints to ensure fair usage.

API throttling prevents API abuse by restricting excessive requests from a single IP address or user. You need rate limiting when protecting public endpoints from being overwhelmed, ensuring service stability and predictable user experiences.

A 429 response means the client exceeded the configured rate limiting threshold. Laravel's throttle middleware returns this status code with Retry-After headers to provide intelligent backoff hints for clients surpassing their per-user limits.
