# E-Commerce API

The Unified Commerce API enables developers and product managers to access e-commerce data from multiple platforms through a single, standardized interface. Retrieve products, inventory, collections, locations, reviews, and sales channel data from Shopify, WooCommerce, BigCommerce, and other major e-commerce platforms - all with one API.

## [What is the Unified Commerce API?](#what-is-the-unified-commerce-api)

E-Commerce refers to the buying and selling of goods and services over the internet, enabling businesses to reach customers globally and conduct transactions digitally. E-commerce platforms like Shopify, WooCommerce, and BigCommerce each have unique APIs with different authentication methods and data models. The Unified Commerce API normalizes these differences.

## [Commerce Data Objects](#commerce-data-objects)

The Commerce API provides access to the following standardized objects:

* **Collections**: Product collections, categories, and catalogs
* **Inventory**: Stock levels, inventory tracking, and warehouse data
* **Items**: Products, SKUs, variants, and product information
* **Locations**: Store locations, warehouses, and fulfillment centers
* **Reviews**: Product reviews, ratings, and customer feedback
* **Sales Channels**: Sales channels, marketplaces, and distribution channels
