Updated 13 April 2023 |

What is eCommerce Marketplace Integration?

The number of eCommerce software providers is growing. More and more companies are starting to offer their inventory management, pricing software, shipping solutions, etc. All of this means that, as a software provider, it’s mandatory to explore the importance of eCommerce marketplace integration development in 2023.

eCommerce marketplace integration means the process of connecting your software with the APIs of marketplaces such as Amazon, Etsy, or eBay. Once the integration is completed, you’ll be able to gain unrestricted access to your customers’ data on each one of these marketplaces. For instance, you’ll be able to work with all the orders or product-related data.

In this article, we’ll dive deeper into how the process of integration with eCommerce marketplaces actually works, and we’ll reveal to you the main benefits of connecting your business with the main marketplaces today.

How Does the Process of Marketplace Integration Development Work?

Tying your software with various shopping platforms involves performing a certain number of tasks. The integration is certainly not an easy procedure, but a complex one that requires specific skills and a lot of time and financial investment.

To be more specific, there are four main stages in the process of marketplace integration:

  • Stage #1: This first stage involves exploring the peculiarities and specifics of each marketplace. At this point, you need to understand that each marketplace has its unique API and bespoke documentation. As a result, integrating your software with each of them is a unique process that requires specific skills. To ensure that you’ll do a fine job, you need to look at the specifics of each marketplace and explore its API documentation.
  • Stage #2: This is when you’re ready to develop an integration between your software and the marketplace. You have two options here: either hire a team of developers or use your in-house developers to manually set up a connection, or utilize a third-party integration service that does the job in your place and connects your system with multiple marketplaces at once.
  • Stage #3: The third stage involves transferring data between the marketplace and your software. This data includes order info, product info, shipping details, taxes, prices, and the list goes on.
  • Stage #4: The last stage involves ongoing support and maintenance of the integration.
