The webhook (URL) is the URL to a custom webhook for the contact.
The following variables are included:
The alphanumeric ID associated with a specific monitor.
This can be found in the URL when on the edit, check, event, and report screens.
The monitor_id is "b74014410cc1236a3d0h7400" (without quotes).
The host/IP for a specific monitor. This does not include the protocol (HTTP/HTTPS) or port.
The alphanumeric ID associated with a specific event that was generated.
Either up or down; all lowercase.
If a 2xx status code is not obtained, we will automatically reattempt the webhook once per hour (up to three tries).
