# meter.created

Occurs when a meter is created.

---

Occurs when a meter is created. A [meter](https://developer.paddle.com/api-reference/meters.md) maps an `action` that you report usage for to the usage balance unit that it draws down.

[`meter.updated`](https://developer.paddle.com/webhooks/meters/meter-updated.md) occurs when a meter changes, including when it's archived.

Payload includes the complete meter entity, plus a `revision_id` for the meter's initial revision.
