  title: Clerk.io Subscribers API
  version: '2'
  description: 'Clerk.io e-commerce personalisation REST API. Ingest and manage catalog data (products, categories, pages, orders, order parcels, customers, accessories), run behaviour-ranked search and predictive search-as-you-type, request recommendation logics (popular, trending, new, complementary, substituting, visitor- and customer-personalised, category- and page-scoped), manage merchandising (custom search configurations, synonyms, redirects), drive audiences/campaigns/subscribers for email, log visitor behaviour events, and service GDPR privacy requests.


    All endpoints live under https://api.clerk.io/v2. Authentication uses a dual-key model: the public `key` identifies the store and is safe in browser-side calls; `private_key` is additionally required for write and sensitive operations and MUST only be sent over SSL.'
