# Request Blocked

Indicates that the request was blocked before it reached the SumUp API service. This can happen when a security policy, firewall rule, or traffic protection rule rejects the request.

## Common Causes

- The request matched a security or firewall rule.
- The request came from a blocked IP address, country, or network.
- The request pattern looked automated, abusive, or otherwise unsafe.
