Tikkivo Catalog Sync is a Shopify app for merchants who receive product data from suppliers. It imports from CSV, XLSX and JSON files, HTTPS feeds, published Google Sheets CSVs and read-only JSON REST APIs, lets you map the fields each supplier controls, and creates new products as drafts. Manual updates show proposed price and stock changes for approval before anything is written, and the page lists its limits, including no XML, FTP or SFTP support in this release.
