# A code passes its expiry without redemption.

`POST access_code.expired` (webhook)

### 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`.

### Related events

- `access_code.redeemed`: alternative outcome.
- `access_code.generated`: predecessor (batch-level).

## Headers

- `SB-Signature` string, required
- `SB-Event-Id` string, required
- `SB-Event-Name` string, required
- `Content-Type` string, required
- `User-Agent` string, required

## Payload

- object: The envelope every event is delivered in.
  - `id` string, 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_at` string, date-time, required: When the event was emitted, server time, ISO 8601.
  - `api_version` string, required: The contract version of the payload shape, `2026-05-01` today. A breaking change to a shape ships under a new version.
  - `project_id` string, uuid, nullable, required: The project the event belongs to; null for team-scoped and billing events.
  - `data` object, required: The event-specific payload. Keys that do not apply to a given emission are omitted rather than sent as null, so check for presence.
    - `plan_id` string, uuid, required: Plan the code was scoped to.
    - `subscription_id` string, uuid, required: Placeholder subscription row that held the unredeemed code.
    - `expired_at` string, date-time, required: When the code became unredeemable.

## Acknowledgement `2XX`

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

## Other responses

- `default`: 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.
