# Limits, timeouts, and system resilience

> Understand rate limits, system timeouts, and how Flux services behave under heavy load.

When integrating with Flux, it's crucial to understand our system limits and how to handle degraded states gracefully.

## Rate limiting

We use **Arcjet** to enforce rate limits across our public endpoints (like Flux Pass) to prevent abuse. When a limit is hit, you will receive a `429 Too Many Requests` response.

### Flux Pass limits

* **Login:** 30 requests per 60 seconds
* **Register:** 10 requests per 60 seconds
* **OAuth callbacks:** 10 requests per 60 seconds
* **Health checks:** 50 requests per 60 seconds

## Timeouts

To ensure system stability, Flux enforces strict timeouts on external integrations:

* **Webhook delivery:** The Webhook Service waits a maximum of **10 seconds** for your endpoint to respond. If your server takes longer, the delivery is marked as failed.
