A route, in its essence, can be seen as a tree-like structure. If an incoming alert has a specific payload that triggers a particular route (branch), a pre-defined integration will be invoked.

There are multiple out-of-the-box integrations available for the most common use cases, such as the following:

• Email
• Hipchat
• PagerDuty
• Slack
• Opsgenie
• VictorOps
• WeChat

There's also the webhook integration that issues an HTTP POST request with the JSON payload of the firing alert to an endpoint of your choosing, opening a world of possibilities for custom integrations.
