# Types of events

This is a list of all public [thin events](https://docs.stripe.com/event-destinations.md#thin-events) we currently send for /v1 and /v2 resources, which are continually evolving and expanding. The payload of thin events is unversioned. During processing, you must fetch the versioned event from the API or fetch the resource’s current state.

## API event types

- [`v1.billing.meter.error_report_triggered`](https://docs.stripe.com/api/v2/core/events/event-types.md?query=v1.billing.meter.error_report_triggered): Occurs when a Meter has invalid async usage events.
- [`v1.billing.meter.no_meter_found`](https://docs.stripe.com/api/v2/core/events/event-types.md?query=v1.billing.meter.no_meter_found): Occurs when a Meter's id is missing or invalid in async usage events.
- [`v2.core.event_destination.ping`](https://docs.stripe.com/api/v2/core/events/event-types.md?query=v2.core.event_destination.ping): A ping event used to test the connection to an event destination.
