What is Laravel API rate limiting and how does it work?

Updated May 16, 2026

Short answer

Rate limiting restricts the number of API requests a user can make in a time window.

Deep explanation

Laravel uses middleware like throttle to control request rates. It tracks requests per user or IP using cache drivers. This protects APIs from abuse, DDoS attacks, and excessive usage. Custom rate limiters can be defined in RouteServiceProvider.

Real-world example

Used in public APIs like payment gateways and SaaS integrations.

Common mistakes

  • Setting too strict limits causing valid users to be blocked.
