BigCommerce Integration: A Complete Developer’s Guide

Updated 21 January 2026 |

BigCommerce is a major player in the eCommerce space, with a huge following among store owners, especially in the United States, Australia, and the United Kingdom. This popularity means that for eCommerce SaaS vendors, developing a robust BigCommerce integration is a strategic move that can unlock a significant number of potential clients. A solid platform integration is no longer a luxury but a necessity for growth. In this article, we will look specifically at the advantages of BigCommerce integration for software developers, the challenges involved, and the streamlined solution available to simplify integration with various eCommerce platforms.

What is BigCommerce Integration?

BigCommerce integration is the process of connecting eCommerce software—such as order management systems, shipping software, or inventory management tools—with the BigCommerce platform. It establishes a two-way communication channel, allowing the software to access and work with essential store data like orders, products, customers, and categories via API. For eCommerce software vendors, this means you can implement various high-value features that BigCommerce sellers need to automate and scale their operations.

Why Your eCommerce Software Needs BigCommerce Integration

Building this connection is a direct route to growing your user base, expanding your market presence, and boosting your bottom line. Here’s what’s in it for your software business:

  • Access to a large and growing customer base: Integrating with BigCommerce gives you a direct line to tens of thousands of established online merchants. This means your SaaS can significantly grow its client base by tapping into a market actively searching for automation tools.
  • Enter new markets: BigCommerce has a strong foothold in key international markets, including the US, UK, and Australia. A reliable integration is your passport to expanding your software's global reach and capturing market share in these high-value regions.
  • Increase revenue and profits: It’s simple math: new clients mean new revenue. The more platforms your SaaS supports, the more potential clients you can attract, which translates directly into a healthier bottom line.
  • Competitive advantage: Each new supported platform puts you one step ahead of your competitors.

Though there are many benefits to developing a BigCommerce integration, there are also significant challenges to consider.

Challenges of Integrating with BigCommerce

If you’re thinking of building a direct integration yourself, be prepared for some serious challenges that can drain your resources and stall your go-to-market plans.

  • Time-consuming: Building a reliable integration from the ground up isn't a quick project. It can easily take a skilled developer several months to learn the API, code the connection, and resolve all the bugs for just one platform.
  • Expensive: The costs add up fast. When you account for developer salaries, infrastructure, and maintenance, a single platform integration can run into thousands of dollars.
  • Complicated: Each eCommerce platform has its own unique API logical architecture, authentication methods, and data formats. Your developers will have to become experts in BigCommerce's specific nuances.
  • APIs often change: Platforms are always evolving. They release new API versions and retire old ones, which means your integration can break without warning, forcing your team into a constant cycle of maintenance.

Fortunately, there is a better way to simplify integration. Instead of wrestling with these direct connections one by one, you can use a ready-made integration solution like API2Cart.

BigCommerce Integration via API2Cart

API2Cart is a unified shopping cart integration service that helps eCommerce software vendors connect with over 40 platforms, including BigCommerce, through a single API. Instead of spending months and thousands of dollars building individual connections, your development team integrates with API2Cart just once. This approach dramatically slashes development time, cuts costs, and frees up your engineers to focus on your core product instead of being bogged down by the complexities of multiple APIs and ongoing maintenance. This makes developing a platform integration with BigCommerce and others far more efficient.

API2Cart’s API Methods for BigCommerce Integration

With API2Cart, you get immediate access to over 100 standardized API methods for managing store data across all supported platforms. For a powerful BigCommerce integration, you can use methods like:

  • product.list/info/count/find/add/update/delete to manage product data.
  • order.list/info/count/find/add/update to work with orders.
  • customer.list/info/count/find/add/update to access and manage customer data.
  • shipment.list/add/update/delete to manage shipping information.
  • category.list/info/count/find/add/update/assign/unassign to handle product categories.

Because these methods work the same way across all supported platforms, your code becomes simpler and your feature development gets a major speed boost. This unified approach to platform integration ensures your connections are always robust, scalable, and easy to manage.
