1. E-Commerce Platform APIs

The question of the best e-commerce platform for online businesses is hotly debated. The good news is that you have plenty of options: the most popular e-commerce platforms include Shopify, BigCommerce, Magento, and WooCommerce, just to name a few.

As your e-commerce site grows, you'll collect more and more data about customer behavior—everything from the products that people put in their shopping cart to the percentage of users who abandon their purchase before checkout. Savvy store owners must harvest and analyze this information, scouring it for hidden trends and insights to help them make smarter decisions.

To do so, you'll often need to process your data with third-party analytics tools and data warehouses. In order to get your data out of your e-commerce platform in the first place, you need a dedicated API for your e-commerce solution. Whether you need a Shopify API, BigCommerce API, Magento API, or WooCommerce API, the "best e-commerce API" here is the one that makes it easy for you to export data from your e-commerce platform and import it into other apps and systems.

Developing APIs can be a complex, time consuming, and expensive process. It can also expose your organization to a number of risks including consistency, quality, and developer resourcing. DreamFactory is a REST API generation platform for a range of databases and other data sources. It gives you the ability to generate secure and fully documented APIs in a matter of minutes.

2. Third-Party E-Commerce Website APIs

In addition to selling products on your own website, you might wish to sell them on a third-party e-commerce store like Amazon, eBay, or Etsy. For maximum efficiency, you'll need an Amazon API or eBay API that your e-commerce platform can easily integrate with. These are the best e-commerce APIs for third-party stores, allowing you to automatically update your storefronts with new products and pricing whenever things change on your main website.

3. Payment Gateway APIs

E-commerce stores need to integrate with payment gateways such as Stripe and PayPal that allow users to make purchases with the payment method of their choice (e.g. credit card, debit card, bank transfer, or even cryptocurrency). The best e-commerce API for payment gateways can automatically connect your e-commerce website's checkout system with a third-party payment gateway that handles these concerns for you. Other benefits of payment gateway APIs include a better user experience and easier fraud prevention.

4. Website Builder APIs

Some e-commerce platforms come with their own website builder tools, but you might also want to use a third-party website builder like WordPress or Squarespace. These solutions make it simpler to build your own website front-end with various plugins and templates, while handling the backend concerns for you under the hood. If you plan on going this route, you'll need one of the best e-commerce APIs so that your website builder tool can communicate with your e-commerce platform. For example, WordPress comes with a REST API so that you can easily access each one of the posts and pages on your website.


Customer relationship management (CRM) software helps your sales, marketing, and customer service teams track each one of their interactions with your customers. By staying on top of each touchpoint and channel—from phone and email to website visits and social media—it will be much easier for you to offer an excellent customer experience. CRM integrations are one of the best e-commerce APIs for online stores to take advantage of. The good news is that CRM platforms such as Salesforce expose their information through an API, so that you can easily export it to a centralized target location (such as a data warehouse or data lake).

As your company grows from small business to worldwide retailer, you need an effective customer support solution without sacrificing scalability. Customer support tools such as Zendesk, Freshworks, and Intercom help you efficiently monitor and resolve queries, issues, and complaints. Because customer support data holds tremendously useful information, you should look for a solution with one of the best e-commerce APIs so that you can export all this data into a third-party analytics tool. You can then track metrics and KPIs to ensure that your customer service remains high-quality at all times.

7. Inventory Management APIs

Last but not least, an inventory management and order management API is one of the best e-commerce APIs for online shopping businesses. Inventory management software helps you keep track of your products' stock levels, so that you can predict issues and resolve them (e.g., by manufacturing more items) before they occur. Order management software helps you track e-commerce orders throughout their lifecycle, from the moment they're placed to the moment they're shipped from your warehouse.
