Webhooks are used by Chartbrew to send chart alerts. Chartbrew also supports sending data to Slack through the Incoming Webhook integration.

​
Webhook chart alerts

Chartbrew sends POST requests to the webhook URL with the following payload:
  • chart - the chart name as a string
  • alert - the alert configuration
    • type - the alert type is one of milestone, threshold_above, threshold_below, threshold_between, threshold_outside, anomaly
    • rules - this is an object that shows the trigger rules for the alert
  • alertsFound - an array of objects containing a label and a value for each item on the chart that triggered the alert
  • dashboardUrl - the URL to the dashboard where the chart is located
Example payload: 
{
  "chart": "Site stats",
  "alert": { "type": "milestone", "rules": { "value": "40" } },
  "alertsFound": [
    { "label": "2023 Jan 13", "value": 47 }
  ],
  "dashboardUrl": "https://app.chartbrew.com/project/1",
  "snapshotUrl": "https://api.chartbrew.com/uploads/1234567890.png"
}

​
Slack webhook

When sending data to Slack, Chartbrew will also attach a blocks property to the payload. This is an array of objects that contain the Slack blocks to be rendered in the message.
