# plan_grant.expired

> A plan grant expired.

## When this fires

After an expired Plan Grant is durably closed by billing discovery or while creating its replacement. The payload is the old grant at expiration, and its last timeline event is `expired`.

`customer.state_changed` also fires with trigger `plan_access_ended` when billing discovery expires the grant.
