  title: Lightspeed Retail R-Series API
  description: |
    OpenAPI 3.1 representation of the Lightspeed Retail R-Series REST API
    (the original Lightspeed Retail / Retail Pro cloud POS). The R-Series API
    is documented at https://developers.lightspeedhq.com/retail/introduction/introduction/
    and exposes account-scoped resources under
    https://api.lightspeedapp.com/API/V3/Account/{accountID}. It uses OAuth 2.0
    with scope-based access control and supports both JSON (`.json`) and XML
    response formats. The numeric `accountID` is not the OAuth client_id; it
    must be resolved via `GET /API/V3/Account.json` immediately after the token
    exchange and is required for every subsequent account-scoped call.
