Configure New Relic alert notification destinations via the NerdGraph API

Steps

1. Create a destination with the aiNotificationsCreateDestination mutation, specifying a type (e.g. EMAIL, WEBHOOK, PAGERDUTY_SERVICE_INTEGRATION, JIRA, SERVICE_NOW, EVENT_BRIDGE, MICROSOFT_TEAMS) plus the auth and properties fields that type requires.
2. List and filter destinations via actor.account(id).aiNotifications.destinations, filtering by name, id, or type, with cursor pagination via nextCursor.
3. Test a destination before or after creation using aiNotificationsTestDestination or aiNotificationsTestDestinationById.
4. Update a destination with aiNotificationsUpdateDestination, supplying only the fields to change.
5. Delete a destination with aiNotificationsDeleteDestination; if it fails because a channel still references it, first query channels(filters: { destinationId: ... }) and delete each with aiNotificationsDeleteChannel.
