# 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
