# A plan is first created on a project.

`POST plan.created` (webhook)

### When this fires

A plan is created through the REST API (`POST /v1/projects/{project}/plans`) or the `create_plan` MCP tool, or a finished pass season is duplicated into its next season. Plans created from the creator dashboard or the bot do not emit this event. The plan is immediately eligible for purchase if it was created in the active state.

> **The two shapes are disjoint.** The API and MCP path sends `data.plan` and nothing else; the season-duplication path sends the four flat keys and no `data.plan` object. Branch on whether `data.plan` or `data.plan_id` is present before reading any other field.

`billing_cycle` is only the unit. The multiplier lives in `billing_cycle_count` on the plan record and is **not** included in this payload: a "3 month" plan sends `billing_cycle: "month"` with no indication of the `3`. Nor is `trial_days`. Fetch the plan with `GET /v1/projects/{project}/plans/{plan}` when you need the full cadence or trial configuration.

### Caveats

- A `plan.created` event does not imply the plan has been synced to a payment-provider catalog. Listen for `plan.sync_completed` for that.
- Trial is configured at create time. A later trial-only edit is only applied, and only then fires `plan.updated`, when the PATCH also carries a `kind` key; without it the trial fields are dropped and no event is emitted.

### Related events

- `plan.updated`: subsequent edits.
- `plan.sync_completed`: provider catalog sync.

## 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` 'plan.created', required: The event name, always `plan.created` 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` object: Sent by the API and MCP path only; absent when a season is duplicated.
      - `id` string, uuid, required: Plan identifier.
      - `name` string, required: Display name.
      - `price` string, decimal, required: Decimal amount as a string, e.g. `"29.00"`.
      - `currency_id` string, uuid, required: Currency row id, **not** an ISO 4217 code.
      - `billing_cycle` 'day' | 'week' | 'month' | 'year' | 'lifetime', required: Billing cadence unit.
      - `active` boolean, required: `true` if the plan is purchasable.
    - `plan_id` string, uuid: Season-duplication payload only. Plan id of the new season.
    - `plan_name` string: Season-duplication payload only. Display name of the new season's plan.
    - `kind` 'subscription' | 'pass' | 'pass_series': Season-duplication payload only. Always `pass_series` on this path, since it clones a series.
    - `duplicated_from_plan_id` string, uuid: Season-duplication payload only. The plan the season was cloned from.

## 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.
