The eBay Connector supports RESTFul APIs which lets you use CIC to connect and integrate data on your eBay business application. The Connector allows users to work with data relating to their eBay application. eBay Connector allows you to connect the CIC to your eBay application data for seamless integration into your Databases, ERP, CRM, and Marketing platforms to keep data aligned between front-end and back-end systems.

How it works in CIC
Using an intuitive Wizard in the Studio, you connect with your external application and then define and configure resources (mainly Business Processes and Schemas) to work with specific APIs. Packages are automatically created; each containing object-specific Business Processes (to call the operation), and Schemas (to build Rulesets).
