The QrX Public API lets merchants create and manage pay-at-the-door transactions, products, returns and webhooks, and run their QrX warehouse: stock levels, items, locations and movements, inbound announcements, receipts, purchase orders, pick lists, counts, containers and team tasks. Authenticate by exchanging your merchant channel API key for a short-lived access token via POST /api/v1/auth/token, then send it as a Bearer token. A key can be restricted to parts of the API (scopes such as stock.read, inbound.write or purchasing.read); a key without restrictions may use every part. Warehouse writes need an Idempotency-Key header.
