# Types of events

This is a list of all the types of events we currently send. We may add more at any time, so in developing and maintaining your code, you should not assume that only these types exist.

## Event types

- `v1.billing.meter.error_report_triggered`
  This event occurs when there are invalid async usage events for a given meter.

- `v1.billing.meter.no_meter_found`
  This event occurs when async usage events have missing or invalid meter ids.
