# Configuring P4 Server event notification

Triggers are still supported, but we recommend you use P4 Server Extensions. P4 Server Extensions are easier to install and maintain than Triggers.

P4 Code Review needs to know about a number of P4 Server events to operate correctly, this can be done by using P4 Server Extensions (recommended) or P4 Server Triggers. P4 Code Review installs include the P4 Server extension file and trigger scripts required for P4 Code Review to get the events it needs from your P4 Server.

You must install and configure P4 Server Extensions or P4 Server Triggers to complete the P4 Code Review installation.

Do one of the following so that P4 Code Review is notified about events on the P4 Server:

- Install and configure the P4 Server extension, see Installing the P4 Code Review extension for P4 Server (recommended)

- Install and configure P4 Server Triggers, see Installing triggers
