  title: Magento REST Authentication Tax API
  description: 'The Adobe Commerce (Magento) REST API provides a comprehensive set of endpoints for interacting with all major aspects of an e-commerce store, including catalog management, orders, customers, inventory, shipping, and payments. It supports three authentication mechanisms: OAuth 1.0a for third-party integrations, token-based authentication for mobile apps and administrators, and guest access for select public endpoints. The API follows REST conventions and returns JSON responses, enabling developers to build integrations, automate store operations, and power headless commerce storefronts. All endpoints are versioned under the /V1 prefix and support searchCriteria query parameters for filtering, sorting, and paginating collection responses.'
