subscription.unpaid

When this fires

A subscription's grace period ends without successful collection. The provider has given up retrying. Resource access is typically revoked shortly after.

This event is emitted for Stripe only — it depends on the provider reporting an unpaid subscription status. On every other provider, an abandoned subscription surfaces as subscription.expired once ends_at passes, with no preceding subscription.unpaid.

Caveats

Expect subscription.expired and member.churned to follow.

subscription.past_due — predecessor inside the grace window.
subscription.expired — terminal state.
