  title: Bold Commerce Checkout API
  description: Bold Commerce provides modular e-commerce APIs for subscriptions, headless checkout, and pricing, plus supporting Products, Customers, and Shops APIs. All requests are made against https://api.boldcommerce.com and authenticated with a Bearer token - either an OAuth 2.0 access token (public integrations, obtained through the Developer Dashboard authorization-code flow) or a scoped API access token (private integrations, generated in the Bold Account Center). Most paths are scoped to a shop_identifier GUID that is retrieved from the Shops API. Versioned endpoints accept a Bold-API-Version-Date header. Endpoints below are modeled from Bold's public developer documentation; request and response schemas are representative.
