# AWS Lambda notifier

The **P0 AWS Lambda Notifier** lets you route notification events directly to your own AWS Lambda function. Built using the [Custom Notifier API](/integrations/notifier-integrations/custom-notifiers.md), it enables you to trigger custom workflows, integrate with internal systems, or run arbitrary logic in response to notification events from your existing AWS infrastructure.

Use it to:

* Trigger automation pipelines
* Forward events to internal alerting systems
* Apply custom filtering or enrichment
* Connect with services beyond email or Slack

## Before you begin

This guide walks you through setting up your **AWS Lambda Notifier.** Before diving into the steps, make sure you have installed an AWS function caller component in P0

[How to install the AWS function caller component](https://github.com/p0-security/p0-docs/blob/main/integrations/resource-integrations/aws/function-caller.md)

## Installing your AWS Lambda Notifier

1. Go to p0.app in your browser, navigate to **Integrations**, and select **AWS Lambda** in the **Notifiers** section.
