member.resource_removed

A subscriber loses access to a specific resource.

When this fires

A subscriber is evicted from a specific resource: after a subscription expires or is cancelled, after a ban, kick or removal, or when a pass window closes or is cancelled. Each resource revocation emits its own event. Nothing is emitted when another still-active subscription of theirs grants the same resource: the invite link is revoked but the member stays in.

Caveats

  • Multiple revocations for the same subscriber typically arrive in close succession when a subscription expires; use SB-Event-Id for dedupe.
  • A manual perk emits this event only when its grant is revoked on the ledger; a place a connector gates emits it once the connector has been asked to remove the member.

Related events

  • member.resource_added: paired transition.
  • subscription.expired, subscription.cancelled, member.kicked: typical triggers.

Ability to subscribe

A token needs this to subscribe an endpoint to the event.

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.

Payload

JSONWhat Subscriby posts to your endpoint

The signed JSON envelope posted to your endpoint.

The envelope every event is delivered in.

Responses

2XXAny success status

Your endpoint acknowledged the delivery. Any 2xx status within 30 seconds marks it delivered; the response body is ignored.

defaultAny other status

Any other status, a connection failure, or no answer within 30 seconds counts as a failed attempt. The delivery is retried 8 times, after 10 seconds, 30 seconds, 2 minutes, 10 minutes, 1 hour, 6 hours, 1 day, 3 days; the last failure dead-letters it, and it can be retried from the dashboard or POST /v1/webhook-deliveries/{delivery}/retry. After 20 consecutive failures the endpoint is paused until it is resumed.
