# Sentry.io
[Sentry](https://sentry.io/) is a developer-first error tracking and performance monitoring platform that helps developers see what actually matters, solve quicker, and learn continuously about their applications.
Route detailed alerts from Sentry to the right users in Squadcast.
### Using Sentry as an Alert Source
1. Navigate to **Services** -> **Service Overview** -> select or search for your Service. Expand the accordion -> In the Alert Sources section, click **Add**.
2\. Select **Sentry.** Copy the displayed **Webhook URL** to [configure](#create-a-squadcast-callback-in-sentry) it within **Sentry**. 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.
{% endhint %}
