    Commerce Layer is a headless, composable commerce platform. The Core API is
    100% compliant with the JSON:API specification (v1.0) and supports compound
    documents, sparse fieldsets, resource linking, filtering, sorting, and
    pagination. All requests are authenticated with an OAuth2 Bearer access
    token obtained from https://auth.commercelayer.io/oauth/token, and access
    tokens may be scoped to a market or stock location. Resources are served
    under the organization subdomain at https://{organization}.commercelayer.io/api
