Catalog

Sync items to Square POS to itemize payments consistently across all channels

The Catalog API allows you to manage your item catalog in Point of Sale, including items, variations, categories, discounts, taxes, modifiers, and more.

You can efficiently sync items between your systems and Square by using our batch APIs, which allow you update many catalog items at once.
