Subscription Status

A subscription can have one of three statuses:

ACTIVE: The subscription is ready to send notifications or is actively sending notifications.

INACTIVE: The subscription has not been activated. Add a health check URL to activate. See Health Check URL.

SUSPENDED: The subscription was active, but the webhook URL or the health check URL became unreachable. When the URL becomes reachable, the status changes to
ACTIVE
and notifications resume.
