Monitor billing assignment requests for shared Capacity Reservations

Amazon EC2 sends Amazon EventBridge events when the state of a billing assignment request changes.

  • Events are sent to the Capacity Reservation owner when a request enters the following states: accepted | rejected | expired | revoked.

  • Events are sent to the requested consumer account when a request enters the following states: pending | expired | cancelled | revoked.

For more information about Amazon EventBridge, see the Amazon EventBridge User Guide.
