# Triggering a Blackhole Policy for the Third-Party System Through the RESTful API

When an anti-DDoS device detects that the traffic of a specified IP address exceeds the blackhole threshold, the ATIC system sends an RESTful API notification to the third-party system for executing a blackhole policy on the upstream network.

#### Context

The blackhole policy can be executed on the DamDDoS and non-DamDDoS system.

- Executing a Blackhole Policy on the DamDDoS
- Executing a Blackhole Policy on the Non-DamDDoS System
- Decapsulating a Blackhole Policy
  The blackhole policy can be decapsulated automatically and manually.
