What are the Shopify APIs?

The Shopify APIs are a set of tools that allow developers to read and write data to a Shopify store, making it possible to build custom apps, unique storefronts, and powerful integrations. There are two main APIs every Shopify developer must know: the Storefront API and the Admin API.

Think of it this way: the Storefront API is for building things that customers interact with, while the Admin API is for building tools that merchants use to run their business. Understanding this distinction is the key to mastering the Shopify developer API ecosystem. This guide will walk you through both, with clear examples to get you started.
