Subscription events are triggered when mailbox subscriptions are renewed, updated, or cancelled. A subscription is the ongoing service that keeps mailbox accounts active after they're created.
Overview#
Subscriptions are separate from domain registrations. Here's the relationship:Domain → Registered once, renewed periodically (yearly)
Subscription → Billing period for mailboxes (monthly, yearly, etc.), can be renewed or cancelled independently

Recommended Actions#
When you receive this event:Notify your customer that their subscription payment failed and they have a 7-day grace window

subscription.expired#
This event is triggered when a subscription's 7-day grace period ends and the subscription has auto-renewal disabled. Mailboxes are deactivated and the subscription is permanently expired.When it occurs#
Subscription has been in PAST_DUE state for 7 days
autoRenew is false — the subscription is not expected to self-recover
Mailboxes are disabled and removed from the provider
Note: If autoRenew is true, the subscription remains in PAST_DUE after the grace period and is not automatically expired — it will be picked up by the renewal mechanism once the underlying issue (payment or domain) is resolved. subscription.expired will not fire for those subscriptions.

Notes#
Subscription and domain are independent — You can have a domain without a subscription, or a subscription without owning the domain (white label)
Auto-renewal can be toggled — Users can enable/disable via dashboard
subscription.updated fires once — It will not repeat on subsequent renewals after the 12-month flag is set
Deduplication — Status events (renewing, past_due, expired, cancelled) are deduplicated: if the subscription is already in a given status, the webhook will not fire again until a different status is reached
subscription.expired requires autoRenew: false — Subscriptions with auto-renewal still enabled are never automatically expired after the grace period; they stay PAST_DUE and retry renewal once payment or domain issues are resolved
