  title: EposNow HQ REST Categories API
  description: The EposNow HQ REST API lets developers programmatically interact with the cloud-based aspects of the Epos Now point of sale (POS) platform for retail and hospitality - products, categories, transactions (sales), customers, stock, tax rates, and devices. This document models the documented V2 API surface (base https://api.eposnowhq.com/api/V2). Epos Now recommends the newer V4 / "Global" API (https://api.eposnowhq.com/api/v4) for new integrations, which reorganizes the same domains; V4 per-resource paths are not fully enumerated here. All requests use HTTP Basic authentication with a per-device access token (Base64 of "API Key:API Secret") issued from the Back Office. List endpoints are paginated at up to 200 records per page via the page query parameter.
