Building an end-to-end shopping experience used to take months. With APIs, adding shopping to apps is possible in a matter of days. Developers can leverage existing platforms and services as building blocks. Therefore, it's crucial to select the appropriate API stack to optimize your app's capabilities and user experience. Here’s an overview of the eCommerce API landscape, our top-picks, and how to choose the right stack for your app.
The eCommerce API Landscape
