If you run an online store on WordPress, a lot of your week probably goes to the same chores: adding products, fixing a price on a variation, creating a coupon for a promotion, looking up a customer, and chasing down an order that needs a refund. WooCommerce lets you do all of it through an API, which is simply a way for other software, or an AI assistant working on your behalf, to make those changes for you. What WooCommerce does WooCommerce is an open-source eCommerce platform built on WordPress. WooCommerce describes itself as the world’s most popular open-source option, and whatever the ranking, the practical point is that it turns a WordPress site into a store. Alongside the store itself it provides a REST API for managing products, orders, customers, coupons, reports, webhooks, and store settings, plus a public-facing Store API for building custom storefronts, and webhooks that announce changes as they happen.
