# AWS CloudWatch Event Rules
[AWS CloudWatch Events](https://docs.aws.amazon.com/AmazonCloudWatch/latest/events/WhatIsCloudWatchEvents.html) delivers a near real-time stream of system events that describe changes in AWS resources. Using simple rules that you can quickly set up, you can match events and route them to one or more target functions or streams.
Route detailed alerts from AWS CloudWatch Event Rules to the right users in Squadcast.
### How to integrate AWS CloudWatch Event Rules with Squadcast
1. Navigate to **Services** -> **Service Overview** -> select or search for your Service. Expand the accordion -> In the Alert Sources section, click **Add**.
2\. Select **Amazon CloudWatch Event Rules**. Copy the displayed **Webhook URL** to [configure](#create-a-squadcast-webhook-in-amazon-cloudwatch) it within **Amazon CloudWatch Event Rules**. Finish by clicking **Add Alert Source** -> **Done**.
{% hint style="warning" %} **Important****:**
When an alert source turns Active, it’ll show up under Configured Alert Sources. You can either generate a test alert from the integration or wait for a real-time alert to be generated by the Alert Source.\
\
An Alert Source is active if there is a recorded incident via that Alert Source for the Service.

A: No, AWS CloudWatch Event Rules does not send auto-resolve signals to Squadcast. Hence, Squadcast incidents from AWS CloudWatch Event Rules should be resolved manually.
