Marketplace API Data

Updated 17 August 2022 |

As an eCommerce software developer, accessing and using marketplace API data is a must if you want to be able to provide your solution customized functionality to your target niche. The data stored on marketplaces such as Amazon, eBay, or Etsy is precious. Without access to it, any eCommerce software cannot automate e-retailers’ business processes properly.

To be able to access all data required, it is mandatory to set up an API connection between your software and various marketplaces. Such integration represents the cornerstone of your growth in the B2B sphere, enabling your solution to expand its functions and provide seamless business operations to your target niche, online store owners who host their sites on marketplaces.

The Importance of Using Marketplace Data

Marketplaces like Amazon, Walmart, eBay, etc., store a vast amount of data belonging to the shops listed on them. To properly run their businesses, merchants who use these marketplaces rely on this data, including product info, customer info, orders, taxes, categories, or shipping statuses. Therefore, the primary importance of your eCommerce software in the retail niche is to offer merchants a high-end solution that would automate their critical processes and enable them to use all this data to grow their businesses efficiently.

The relevant data stored on marketplaces include:

  • Customer information (address, name, email address, phone number)
  • Order info (status, number)
  • Product info (product image, ID, price, description, quantity)

As an eCommerce software provider, this data is necessary for you to propose your services to e-shop owners.

For instance, marketplace API data integration between a multichannel software and Etsy or Amazon will enable the former to create product lists across multiple channels with ease and then add, update or delete product information from the partner sites automatically.

Diving Deeper Into Marketplace API Data Integration

Marketplace API data integration represents the process of setting up a reliable connection between any eCommerce software and numerous online marketplaces. Once the connection has been set up, the software will be able to access the data stored on the marketplaces. This integration allows two applications to connect with each other and transfer data with the help of an API.

Marketplace API data integration is highly beneficial for software providers looking to expand their services and reach new clients. The more marketplaces you integrate your solution with, the higher the number of prospects you can get. The list of customers also includes international businesses that have localized websites across multiple geographies.

A huge advantage of such an integration for your company is the profit it can bring over to you. A higher number of clients equals an increase in ROI, which translates into growth for your company in the long run.

Nevertheless, accessing the marketplace data is a tricky task, as the process of integrating your software with a marketplace API can be quite complex. Some of the integration challenges you might expect along the way include:

  • A single connection can cost anywhere from $3000 to $10k, excluding the cost of maintenance, setup, and infrastructure
  • In addition to the time it takes to find the right team for the job, you’ll also have to wait around 8 weeks for integration to complete
  • An integration is not ready when the developers complete the process, but it requires constant maintenance, bug fixing, and improvement
  • You can multiply the time and financial investment it takes for a single integration with the number of platforms you want to get connected to
