Client Health Check

The health-check handler is an implicit mandatory webhook handler that all clients must implement.

This webhook handler is implicit in the sense that the school does not need to explicitly register the health-check handler. The health-check URL is automatically formulated from the service-provider's base URL. The health-check handler is automatically subscribed to health-check events when the service-provider is enabled and at least one of its capabilities is also enabled. It is automatically and implicitly unsubscribed from health-check events when the service-provider is disabled or all of its capabilities are disabled.
