Using BigCommerce’s powerful APIs, SDKs, and toolkits, developers can build apps that are installable on BigCommerce stores. Once approved, apps can be sold (or made available free of charge) to all BigCommerce merchants on the App Marketplace. This is the first article in a comprehensive developer’s guide to building BigCommerce apps. It provides a brief, high-level introduction for developers new to the platform. If you already have experience developing for BigCommerce, feel free to skip ahead or check out the quick start tutorial.

Let’s first take a look at how apps are discovered, displayed, and managed on BigCommerce stores.
Approved apps are listed on the App Marketplace for merchants to browse, search, and install.

Apps installed on a store are managed in the store’s control panel under Apps > My Apps. Here, store users can launch or uninstall the app.

When a merchant launches an app, BigCommerce makes a request to the app’s /load callback and displays the app’s UI in an iFrame.
