Alerts can be delivered using a webhook. When configured this way, Amberflo will make an HTTP POST request to the specified endpoint whenever the alert threshold condition is met.

The request will contain a JSON payload with the relevant alert information. If the endpoint responds with a 200 status code, the delivery is considered successful. Any other status code will be treated as a failure, and the system will retry sending the alert.

## Context Variables

The following context variables can be used to set a webhook request header and payload:

## Sample Webhook for Slack

Create the alert using the [Alerts UI](https://ui.amberflo.io/alerts/create):

Alerts will send the following HTTP request to the **webhook endpoint**:

--data-raw '{
