SamCart Subscriptions API

  title: SamCart Public API
  description: >-
    The SamCart Public API (v1) provides programmatic access to a SamCart
    marketplace's commerce data - orders, products, customers, subscriptions,
    charges, and refunds - over REST at https://api.samcart.com/v1. Read
    endpoints return lists and individual records; write endpoints cancel or
    schedule cancellation of subscriptions, issue full refunds against charges,
    and update order custom fields. Authentication uses an API key passed in the
    `sc-api` header. API keys are provisioned by the SamCart Support team
    (contact support@samcart.com); the API is not fully self-serve.

    NOTE: This description is modeled by API Evangelist from SamCart's public
    documentation, knowledge base, and third-party integration guides. Resource
    names, the base URL, the sc-api authentication header, and the presence of
    orders / products / customers / subscriptions / charges / refunds endpoints
    are grounded in those sources. Exact path segments, query parameters, and
    schema fields are honestly modeled to REST convention and should be verified
    against developer.samcart.com. Endpoints are marked with
    `x-endpoint-modeled` where the precise path or shape is inferred.

    API keys are generated by the SamCart Support team on request
    (support@samcart.com); access has historically been gated to a beta program
    and higher plan tiers rather than being fully self-serve.
