Any SaaS app provider needs to be able to connect to multiple shopping platforms, especially if they want to diversify and grow their client base and provide superior services to their end customers. eCommerce B2B software providers have even more reasons to provide flawless shopping platform API integration because their main customers can be found on modern shopping platforms.

Retailers need to maximize their businesses and automate their processes, so they start using certain services. They need help from SaaS app providers in accounting, inventory management, warehouse management, order tracking, e-mail marketing, and numerous other systems. However, you cannot offer your services to eCommerce store owners without being integrated with the platforms that they use.

In simpler terms, you cannot provide marketing automation services, pricing software, or any other service you offer, without being integrated with the shopping platforms used by your customers. For instance, if you want to target eCommerce shop owners that are using Amazon or Walmart, you cannot offer them professional services until you don’t integrate your system with Amazon and Walmart. That’s why you need an API to integrate your company with multiple shopping platforms.

What is an API and How it does it Work?

To better understand the importance of integrating your business with shopping platforms, it is crucial to understand what an API is and how it works. Also known as an Application Programming Interface, it acts as an intermediary between two applications or digital products. The API works as a messenger, delivering your request to the other app and then coming back with an answer.

The API is created to automate repetitive tasks and make it easy for you to request and send information. Developers can create an API from scratch, or they can build upon blocks of code already created to make the API better and improved. A well-developed API allows the systems to communicate with one another quickly and reliably, without any loss of data.
Moving further down the path, a REST API is a more advanced API that enables the users to perform increasingly flexible multi-provider architectures.

So how does an API work? To better understand this concept, all you have to do is imagine a waiter at a restaurant. As the customer, you are sitting comfortably at a table, with the menu in front of you. You simply call the waiter and order something on the menu. The waiter goes to the kitchen, sends your order, and then comes back with the food once it has been prepared. The waiter is the API in this case.

With an API, you can access the information regarding your customers’ products that are stored in the database of eCommerce platforms. However, because most shopping platforms have their own APIs, it becomes quite a tedious task to integrate with multiple APIs at once. It would be best if you had an API that allows you to integrate with the most important shopping cart software, such as WooCommerce, Magento, PrestaShop, OpenCart, Shopify, Amazon, Walmart, or eBay.

Shopping Platform API Integration

For you, as a SaaS provider in the B2B market, it is essential to have robust integrations with numerous eCommerce platforms. For example, if you want to target shop owners who are selling on VirtueMart and are using ZenCart, you need to be connected via API to these two providers.

While you should focus on integrating your services with the biggest platforms out there, you should not neglect smaller platforms. The biggest eCommerce platforms are Shopify, Etsy, WooCommerce, Magento, OpenCart and BigCommerce.

The benefits of shopping platform API integration are many. First, you can dramatically increase your customer database, since you’ll be able to gain integration to a wide range of platforms. Second, you’ll be able to offer superior services to your end customers, streamlining their processes and allowing them to easily manage all the information related to orders, stocks, taxes, products, and shipments. Third and last, you’ll manage to get a boost in profits and set yourself apart from the competition.

When it comes to integration, you have multiple options. The first one is doing the integration manually, with each platform. This option takes a lot of time, costs a lot of money and has a high failure rate. Even if you focus on just two platforms, such as Magento and WooCommerce, you’ll have to spend thousands of dollars and months until you get to successful integration, plus you have to invest hundreds of dollars each money on management and improvement.

The other option you have is to use an API that seamlessly integrates your SaaS business with all the important eCommerce platforms at once. That’s where API2Cart comes in. We offer a unified API that allows you to enjoy quick integrations with over 40 shopping platforms and marketplaces.
