[🔗](https://github.com/jeffhuen/tiger_stripe/blob/main/lib/stripe/params/v2/billing/meter_event_create_params.ex#L2)

Parameters for meter event create.

# `t`

```elixir
@type t() :: %Stripe.Params.V2.Billing.MeterEventCreateParams{
  event_name: String.t(),
  identifier: String.t() | nil,
  payload: %{required(String.t()) =&gt; String.t()},
  timestamp: String.t() | nil
}
```

* `event_name` - The name of the meter event. Corresponds with the `event_name` field on a meter.
* `identifier` - 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.
* `payload` - 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#payload-key-overrides).
* `timestamp` - 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. Format: date-time.
