member.churned

A subscriber's last active subscription lapsed.

Ability to subscribeproject-user:view

When this fires

A subscriber's last subscription is expired (by the five-minute expiry sweep, by a refund that ends access, or by a cancelled pass window) and no other subscription of theirs is still active. A cancellation or a failed payment does not churn the member on its own; churn follows only once the subscription is actually expired.

Caveats

  • A subscriber with multiple overlapping subscriptions does not churn until the last one ends.
  • member.churned does not delete the subscriber row; if they re-subscribe later, a paid checkout emits subscription.activated and an access-code redemption emits member.joined.

Related events

  • subscription.expired: typical predecessor.
  • member.joined: only if they return via an access code.

Header Parameters

SB-Signature*string

t=<unix seconds>,v1=<hex>: the HMAC-SHA256 of "<t>.<raw body>" under the endpoint's secret. Verify it before acting, and refuse a t more than 300 seconds from now. During a secret rotation a v0= signature under the previous secret may precede v1=.

SB-Event-Id*string

The event's ULID, bare. The envelope's id is the same ULID prefixed evt_, so strip the prefix before comparing. Deduplicate on it: a retry carries the same id.

SB-Event-Name*string

The event name, the same as the envelope's type.

Content-Type*string

Always application/json.

User-Agent*string

Always Subscriby-Webhooks/1.0.

Request Body

application/json

The signed JSON envelope posted to your endpoint.
