# Integrations

> Connect the SaaS your team uses through Unified.to, react to its events, call its API from a tool, or add a catalog commerce or booking app

This section covers everything that connects an [agent](/concepts/agents) to a third-party system with the credential held by the platform: for developers whose agent must read or write a SaaS product, and for the product team that owns a shop or a booking calendar. Unified.to [integrations](/concepts/integrations) are connected and managed with `lua integrations`; the four catalog apps are connected outside the CLI (an app store listing, a WordPress plugin, a browser authorization, or support) and come with their own commerce or booking tools.

Which family: if the product is listed by `lua integrations available`, connect it with the CLI; if it is Shopify, WooCommerce, Square, or SimplyBook.me and you want the synced catalog, baskets, or booking tools, use the catalog app (Shopify and WooCommerce exist in both families, Square and SimplyBook.me only as catalog apps).
