Use this guide to install PayPal’s Store Sync App in BigCommerce and connect your product catalog to AI shopping surfaces. PayPal’s Store Sync App syncs your product catalog with PayPal’s agentic commerce platform, making your products discoverable and purchasable through AI assistants such as Microsoft Copilot, Perplexity, and PayPal Assistant. After you install the app, PayPal automatically syncs your catalog across AI surfaces.
