The eCommerce industry is rapidly driving on the wheels of evolution. That said, eCommerce software vendors are already in for a battle to serve their clients better. Owing to the increasing number of software vendors in the market, the need to withstand the competition demands these vendors to be one step ahead in what they offer.

This API integration tutorial is for eCommerce software vendors looking to expand their horizons and gain an edge in the competition while offering the best to their clients.

API integration enables the software vendors to connect their eCommerce software with shopping platforms like Magento, Shopify, WooCommerce, OsCommerce, WP e-Commerce, Amazon, CommerceHQ, eBay, to name a few. This integration allows the software providers to provide the necessary functionality of their applications to their clients. It works as a bridge of data transfer between shopping platforms and the eCommerce software.

If you are unaware of what an API is and how API integration works, this API integration tutorial is your go-to source. Let’s get started.

What is API Integration?

An API (Application Programming Interface) is a machine-readable interface that enables software products to communicate with each other and exchange data. In technical terms, it is a set of programming statements that facilitate data transmission between software products.

As an eCommerce software provider, you can interact with external applications with the help of APIs. An API also allows you to add specific functionalities to your software to trigger the development process.

The connection between the APIs of two or more applications is therefore known as API integration. This integration allows two systems or software to interact with each other and exchange various types of data.

API integration enables eCommerce software vendors to equip their application functions with other systems and apps to enhance their functionality. In this API integration tutorial, you will also get to know how an API integration works and how it helps eCommerce software providers achieve their goals.

How Does an API Integration Work?

Going forward with the API integration tutorial, we will now see how this communication takes place between the APIs.

API integration, in simple terms, translates the incoming requests and outgoing responses to enable communication between the two connected functional units. The requests coming from a data source to the API must be translated into a compatible form, so the outgoing response is understandable. An API integration, therefore, makes the two API layers talk to each other and exchange data. In this way, the data can be synced across layers (applications) connected with each other.

In the eCommerce sphere, the eCommerce software providers have a dire need for eCommerce API integrations to connect their solutions with shopping platforms and marketplaces like Amazon, WooCommerce, Magento, Neto, Shopify, CommerceHQ.

eCommerce API integration is the process of connecting these B2B eCommerce software with shopping platforms so the former can perform its functionality with the help of e-store data retrieved from the shopping platforms.

The ability to get and work with shopping platforms’ data connected with products, prices, orders, etc., is essential for eCommerce software providers who operate in the spheres of:

  • Mobile Commerce APP Development
  • Order and Inventory Management
  • Repricing and Price Optimization
  • Dropshipping Automation
  • Product Information Management
  • Marketing Automation
  • Warehouse Management
  • Multi-Channel Commerce
  • Point of Sale
  • Product Catalog
  • Shipping Management
  • ERP
  • Chatbots
  • POS
  • Social Commerce

These solutions need access to the platforms’ e-store data to be able to perform their specific functions seamlessly and help the store owners to ease their business operations. Further, this API integration tutorial explains what it takes to develop an eCommerce API integration.

How Long Does it Take to Integrate with APIs of eCommerce Platforms?

Every eCommerce platform has its own API. That means there is a specific API layer that allows the shopping platform to interact with other applications. Each of them has a specific logic and architecture.

Further, as an eCommerce software provider, your clients have e-stores on multiple platforms, including Shopify, Magento, WooCommerce, BigCommerce, and more. You have to connect your software with every platform on which your clients have built their stores. API integration development with only one shopping platform can take a month or more to complete. You can now imagine the time it will take to develop integrations with all the shopping platforms that are on your list.

Moreover, shopping platforms keep upgrading their APIs to resolve security issues. Hence, you will need to upgrade your integrations, too. Add on the time, money, and resources you will require to facilitate the maintenance and updating.

But, if you opt for a third-party solution instead of an in-house development team for establishing multiple eCommerce API integrations, the scenario can be different.

API2Cart is one such third-party service. It provides a unified API that allows its clients (B2B eCommerce software providers) to connect their software and applications with more than 40 shopping platforms and marketplaces in just one go.

API2Cart leverages REST API to help your application communicate with shopping platforms. With API2Cart, there’s no need for separate integrations, updates, and maintenance. You just need to integrate your software with API2Cart, which in turn connects with all the shopping platforms you wish to integrate your software with.

With API2Cart, access to important store data from these shopping platforms is no longer a big deal. You can even retrieve, add, delete, and modify data from the various e-stores easily and quickly.
