method: derived
source: openapi/lightspeed-k-series-openapi.json (webhooks block), openapi/lightspeed-x-series-openapi.json
  (WebhookType enum + /webhooks operations)
asyncapi_published: false
note: 'Lightspeed publishes no AsyncAPI document. It does publish a real, machine-readable webhook surface
  in two places: the K-Series OpenAPI 3.1 `webhooks` block (11 typed inbound callbacks with full payload
  schemas) and the X-Series WebhookType enum (7 event types, subscribable through the /webhooks CRUD operations).
  This artifact captures both verbatim from the specs; nothing here is authored. A fetch of the X-Series
  webhooks guide page returned HTTP 429 from the ReadMe docs host and was not retried, so prose detail
  from that page is absent.'
products:
- product: X-Series
  api: lightspeed:retail-x-series
  subscription_model: CRUD via /webhooks (POST creates, GET lists, PUT updates, DELETE removes); one URL

  note: Declared in the OpenAPI 3.1 `webhooks` object, so each callback carries a full request-body schema
    — the closest thing Lightspeed ships to an event contract.
gaps:
- No AsyncAPI document for any product line.
- No published event catalog, retry policy or delivery-guarantee statement for X-Series webhooks.
- No webhook signature/verification scheme documented on either product line; K-Series ships an idempotency
  key but no HMAC signature.
- eCom C-Series documents webhooks in prose (https://developers.lightspeedhq.com/ecom/tutorials/webhooks/)
  but publishes no machine-readable event list; not captured here.
