access_code.* events

A code passes its expiry without redemption.

When this fires

An access code passes its expiry without being redeemed. The placeholder subscription row holding it is hard-deleted immediately after this event is emitted.

The code string itself is not included on this event; only access_code.redeemed carries access_code. The placeholder row referenced by subscription_id is hard-deleted immediately after this event is emitted, so it will not resolve through the API.

Caveats

  • Expiry is detected by a sweep that runs every five minutes, so created_at trails expired_at by up to five minutes plus queue latency.
  • Large batches may produce a sustained burst of access_code.expired events when the batch hits its expiry. Plan capacity accordingly.
  • Codes that were already redeemed do not produce this event regardless of the batch's expires_at.

Headers

SB-Signaturestring required

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-Idstring required

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-Namestring required

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

Content-Typestring required

Always application/json.

User-Agentstring required

Always Subscriby-Webhooks/1.0.

Payload

idstring required

A ULID unique to the event, prefixed evt_. Every retry carries the same id, so it is the key to deduplicate on.

type'access_code.expired' required

The event name, always access_code.expired here.

created_atstring date-time required

When the event was emitted, server time, ISO 8601.

api_versionstring required

The contract version of the payload shape, 2026-05-01 today. A breaking change to a shape ships under a new version.

project_idstring uuid nullable required

The project the event belongs to; null for team-scoped and billing events.

Response

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

Changes

Webhooks have no change history: a webhook is keyed by its event name rather than a path and method, so no recorded change can name it.
