NewRelic alerts in MS Teams

In MS Teams:

If necessary, create a team and add members

Add a channel to the team where alerts will be sent

Add a "Incoming Webhook" connector to the channel
- Give it a name
- Upload an icon (not critical, but helpful later for quickly telling alerts apart)
- note the WebhookURL


In New Relic:

Goto Alerts | Notification Channels

Add a Webhook channel

- Give it a name
- Set Base URL to MS Teams WebhookURL
- Set custom payload:

{
  "account_id": "$ACCOUNT_ID",
  "account_name": "$ACCOUNT_NAME",
  "closed_violations_count_critical": "$CLOSED_VIOLATIONS_COUNT_CRITICAL",
  "closed_violations_count_warning": "$CLOSED_VIOLATIONS_COUNT_WARNING",
  "condition_family_id": "$CONDITION_FAMILY_ID",
  "condition_name": "$CONDITION_NAME",
  "current_state": "$EVENT_STATE",
  "details": "$EVENT_DETAILS",
  "duration": "$DURATION",
  "event_type": "$EVENT_TYPE",
  "incident_acknowledge_url": "$INCIDENT_ACKNOWLEDGE_URL",
  "incident_id": "$INCIDENT_ID",
  "incident_url": "$INCIDENT_URL",
  "metadata": "$METADATA",
  "open_violations_count_critical": "$OPEN_VIOLATIONS_COUNT_CRITICAL",

}

Notes: 
"title" and "text" are the important fields here, and are not provided in the template payload.
"text" can accept multiple parameters, literal strings and newlines - e.g. "text": "Hello World\n\r$EVENT_DETAILS\n\r$EVENT_STATE"
