# event_notification_webhook_handler.rb - receive and process event notification like the
# v1.billing.meter.error_report_triggered event.
#
# In this example, we:
#     - create a StripeClient called client
#     - use client.parse_event_notification to parse the received event notification webhook body
#     - call client.v2.core.events.retrieve to retrieve the full event object
#     - if it is a V1BillingMeterErrorReportTriggeredEvent event type, call
#       event.fetchRelatedObject to retrieve the Billing Meter object associated
#       with the event.
