What is an eCommerce API?

An API, or Application Programming Interface, acts as a messenger between different software applications. It defines a set of rules and specifications that allow authorised applications to communicate and exchange data seamlessly.

How do eCommerce APIs work?

For eCommerce, APIs play a critical role in connecting various systems behind the scenes. This ensures a smooth and efficient shopping experience for customers. For instance, an API can connect your online store to your inventory management system, automatically updating stock levels when a shopper adds to cart or makes a purchase. It can also facilitate secure communication with payment gateways for seamless transactions.

This constant data exchange, facilitated by APIs, ensures everything runs smoothly.

Examples of APIs in eCommerce?

Here’s a closer look at some of the most common types of eCommerce APIs:

  • Catalog API: This manages your product information. You can use it to create, edit, and update product details, descriptions, images, and stock levels.
  • Login API: This API handles user authentication and authorisation. It allows customers to securely log in, manage their accounts, and access personalised recommendations or purchase history.
  • Cart API: This API controls the shopping cart functionality. Customers can add, remove, and update items in their cart, and the API ensures accurate price calculations and stock availability checks.
  • Checkout API: This API streamlines the checkout process. It allows customers to enter their shipping and billing information, select payment options, and securely complete their purchases.
  • Payment API: This API connects your store with a payment gateway, enabling secure and trusted transaction processing.
  • Shipping API: This API integrates with shipping carriers, allowing you to calculate real-time shipping rates and display accurate delivery options to customers.
  • Social Proof API: This API allows customers to see which products are popular, trending, bestselling, how many shoppers have added to cart and more.
