# Rate Limiting

BundleUp enforces **rate limits per connection** to protect upstream APIs, ensure fair usage, and prevent a single customer from overwhelming an integration.

Rate limiting is strict, predictable, and enforced at the proxy layer.

### **Rate limit policy**

Each **connection** is limited to:

* 100 requests
* per 60 seconds

This limit applies independently to every connection.

### **What happens when you hit the limit**

When a connection exceeds its rate limit:

* The request is rejected with **429 Too Many Requests**
* No request is sent to the upstream API
* The response includes a `Retry-After: 60` header indicating when you can retry
