  title: OpenCart REST Affiliates Orders API
  description: 'The OpenCart REST API enables external applications to communicate with a self-hosted OpenCart store. It provides endpoints for managing the shopping cart, customers, orders, addresses, shipping methods, payment methods, subscriptions, and affiliates. Authentication is performed by submitting API credentials to receive a session token, which must accompany subsequent requests. IP-allowlist enforcement is applied at the store level.
