Why API2Cart
What our customers say
We LOVE you guys, thanks for everything your support team has been doing for us!!!
We use Api2Cart for our customer integrations and have found them to be very helpful and responsive to any issues we have faced. Integration across so many variants and versions of shopping carts gets complicated very quickly and their expertise has helped us smooth over this process. I would recommend them to anyone looking to simplify their integrations.
Consistently Amazing - …the API and the infrastructure we use for shopping carts is built by a solid software engineering team we've known for years. Salesorder.com is a mission-critical order management platform for wholesalers. Our due diligence selected API2Cart as the best in its class. They’ve connected over 50 carts. It’s how they earn their living, and they’re probably best there is on Earth at cart integration and supporting a critical part of your business.
I have been using API2Cart since beginning of 2014 for our new webstores product. We have successfully integrated close to 100 stores and are currently doing 5 new stores every week. We started with the standard plan (shared hosting) and in 2015 we upgraded to a dedicated server to increase the number of monthly and concurrent API requests. As an ecommerce company with more than 20,000 online sellers security is very important for us. During the time that we have used API2Cart we have not had any problems related to security. The support that API2Cart provide us with is excellent. Communication is quick and the expertise from their engineers have helped us to successfully integrate API2Cart with our own platform.
We use API2CART now for more then a year. Several customers of our application are succesfully connected to this platform. So far we are very happy with the product and the service as well! Keep up the good work!
We have been working with you now for nearly 2 years now and your support is fantastic, one of the best I have worked with plus we have never had any security issues with you.
An API connection to shopping carts is the best way to work with merchants. Managing all those connections is a lot of work and requires a lot of knowledge. By using API2Cart we don't need to spend the time and effort to create and maintain all these connections.
Cooperation with API2Cart is a great opportunity for UniSender to become more accessible for e-commerce platforms users. For us it’s fast and profitable since API2Cart supports integration with dozens of shopping carts thus providing secure and reliable integration. For our users it’s even more opportunities to quickly and securely transfer their client’s contact information from the most popular platforms into UniSender and start an e-mail marketing campaign immediately.
Thank you, API2Cart. Your API has helped us integrate with a new platform. You are a big part of our success.
So far API2Cart has been great! Simple and functional. I really liked the collector class from the code sample. It’s so easy to call the functions I want through that.
At AppsBuilder we have been using API2Cart for over a year and so far over 100 of our clients have successfully used it to connect to the eCommerce provider of their choice. We have found the security of API2Cart to be excellent, and are confident that our clients' data and that of their customers in turn is more than adequately protected. We have certainly not encountered any problems of a security nature and nor do we expect to.
API2Cart enables us to support synchronization to any of the e-Commerce carts that our customers use. This means we can focus on what we do best, enabling turnkey mobile commerce applications.
We are delighted to be working with API2Cart and be able to offer our mCommerce solution to hundreds of thousands of eCommerce store owners looking to go mobile. Being invited as part of the API2Cart network means any eCommerce store owner can easily synchronise their store with MobiCart.
We have finally succeeded in getting our first client adding the store to API2Cart. And the API worked! Pure magic. I simply press the button and receive all the necessary information. This thing is really awesome.

Why is marketplace integration critical for modern eCommerce software?
First of all, marketplace integration allows eCommerce software to centralize orders, products, and customer data from multiple sales channels. Moreover, as marketplaces like Amazon, eBay, and Walmart continue to dominate online sales, software without marketplace connectivity quickly loses relevance. As a result, unified integration helps SaaS providers scale faster and reduce operational complexity. For a deeper overview of this approach, you can explore the Marketplace API integration guide.
How does API2Cart simplify integration with multiple marketplaces at once?
Instead of building separate connectors for each marketplace, API2Cart provides a single API to work with orders, products, customers, and inventory across 60+ platforms. Consequently, development teams implement one integration and reuse it for all supported marketplaces and eCommerce platforms. In addition, API2Cart handles platform-specific API changes, which significantly reduces long-term maintenance costs. This approach is especially valuable for operational use cases such as support and order handling, as described in the eCommerce call center integration use case.
What types of store data can be synchronized through marketplace integration?
Typically, marketplace integration enables software to retrieve and sync key entities such as orders, products, customers, shipments, and inventory levels. Furthermore, this data can be updated in real time, ensuring consistency across all connected sales channels. As a result, SaaS products can support automation scenarios like order routing, stock synchronization, and customer support workflows. This unified data access is one of the core advantages of using an API-driven marketplace integration strategy.
Who benefits most from easy marketplace integration via a unified API?
Primarily, this approach benefits SaaS providers building order management, shipping, inventory, analytics, and multichannel solutions. Additionally, agencies and service platforms gain the ability to onboard new merchants faster without custom development per marketplace. Ultimately, a unified marketplace integration enables faster time-to-market while keeping integrations stable as platforms evolve.
