  title: Loyverse Categories Items API
  description: REST API for the Loyverse point of sale (POS) platform. Loyverse is a free POS for small retail stores, cafes, bars, and restaurants; this API exposes the same data as the POS and Back Office - items and variants, categories, receipts (sales), customers and loyalty, inventory levels, stores, employees, payment types, taxes, discounts, modifiers, suppliers, POS devices, and shifts. All endpoints are HTTPS REST with cursor-based pagination. Authenticate with a personal access token (Bearer) generated in the Back Office, or with the OAuth 2.0 authorization-code flow for third-party apps acting on behalf of other merchants. This document is derived from the public Loyverse API reference and grounds real endpoints; request and response schemas are summarized and should be verified against the live reference during reconciliation.
