/**
 * Meter events represent actions that customers take in your system. You can use meter events to bill a customer based on their usage. Meter events are associated with billing meters, which define both the contents of the event’s payload and how to aggregate those events.
 *
 * @property string $object String representing the object's type. Objects of the same type share the same value.
 * @property int $created Time at which the object was created. Measured in seconds since the Unix epoch.
 * @property string $event_name The name of the meter event. Corresponds with the <code>event_name</code> field on a meter.
 * @property string $identifier A unique identifier for the event.
 * @property bool $livemode If the object exists in live mode, the value is <code>true</code>. If the object exists in test mode, the value is <code>false</code>.
 * @property \Stripe\StripeObject $payload The payload of the event. This contains the fields corresponding to a meter's <code>customer_mapping.event_payload_key</code> (default is <code>stripe_customer_id</code>) and <code>value_settings.event_payload_key</code> (default is <code>value</code>). Read more about the <a href="https://docs.stripe.com/billing/subscriptions/usage-based/meters/configure#meter-configuration-attributes">payload</a>.
 * @property int $timestamp The timestamp passed in when creating the event. Measured in seconds since the Unix epoch.
