# Integrations

WCPOS runs on the WooCommerce REST API, so most WooCommerce plugins work with POS orders without any extra setup. A few need WCPOS to do something on their behalf, because they only hook into the online checkout or the WP Admin order screen. The pages in this section cover those plugins: what WCPOS does for them, how to set them up, and what to expect at the till.

This is different from [Extensions](/fr/extensions/.md), which are add-ons built for WCPOS that you install from the extension directory. An integration is a plugin you already run for your online store.

If a plugin you rely on misbehaves with the POS, start with [Plugin Conflicts](/fr/support/troubleshooting/plugin-conflicts.md): it lists known conflicts and how to identify a new one.
