Webhook body

The JSON that a webhook channel receives for each incident, maintenance, announcement and detected outage.

A channel of the tool Other tool (webhook) receives a POST with a JSON body at the address you give it: Zapier, Make, n8n, Power Automate, Home Assistant or a script of your own. See Alerts for the channels themselves.

Fields

`happening`

What took place: opened, updated, rescheduled, started, closed, published, reviewed, service_down, service_up or test. reviewed is the report written once an incident is resolved, sent once; message.text holds its start. test is the message of Send a test.

`event`

kind: incident, maintenance or publication (an announcement).
severity: minor or critical, for an incident.
category: changelog or info, for an announcement.
state: the state the event moved to.

event is null for an outage the checks found. The body then carries, at its top level beside service, a services list with one entry for each service of that wave: [{"name": "Mail", "down_since": "2026-10-07T08:57:00Z"}]. The body of an event has no such list: its services are the names in event.services.

`service`

When an outage the checks found is about one service alone, service holds that same entry. It is null for a wave of several services, and in the body of an event, as in the example above.

`message`

The text the chat tools receive, in the language of the channel. mark is outage, degraded, maintenance, restored or plain.

Stability

Dates are in UTC. A later version of the body adds fields without changing these.
