Our technology recommendation around market place connections

We have many years of experience in connecting marketplaces to a wide range of store systems. In the following, we would like to introduce you to the marketplace connection options with Shopify, Shopify Plus and Shopware. 



The Shopware Markets extension provides the ability to offer products on ebay and Amazon. The extension automatically posts products to the affected marketplaces based on your merchant accounts. In addition, orders received via these marketplaces are transferred directly to Shopware and can be managed under Orders. Each marketplace is mapped via its own sales channel, in which the configuration is carried out. 


Shopify & Shopify Plus 

Marketplace integration can be done in Shopify in two ways: 

  • Shopify Apps: These are Shopify reviewed apps that can be listed in the Shopify Appstore by the vendor. Integration occurs when the app is downloaded. 
  • API Connections: This is an integration through a programmed interface to exchange data between Shopify and external systems. Integrations like these usually have to be provided by the marketplace provider.
