# Create a Meter Event with asynchronous validation

Creates meter events. Events are processed asynchronously, including validation. Requires a meter event session for authentication. Supports up to 10,000 requests per second in livemode. For even higher rate-limits, contact sales.

## Parameters

- `events` (array of objects, required)
  List of meter events to include in the request. Supports up to 100 events per request.

  - `events.event_name` (string, required)
    The name of the meter event. Corresponds with the `event_name` field on a meter.

  - `events.payload` (map, required)
    The payload of the event. This must contain the fields corresponding to a meter’s `customer_mapping.event_payload_key` (default is `stripe_customer_id`) and `value_settings.event_payload_key` (default is `value`). Read more about the [payload](https://docs.stripe.com/billing/subscriptions/usage-based/recording-usage.md#payload-key-overrides).

  - `events.identifier` (string, optional)
    A unique identifier for the event. If not provided, one will be generated. We recommend using a globally unique identifier for this. We’ll enforce uniqueness within a rolling 24 hour period.

  - `events.timestamp` (timestamp, optional)
    The time of the event. Must be within the past 35 calendar days or up to 5 minutes in the future. Defaults to current timestamp if not specified.
