The purpose of the connector is to enable hassle-free syncing of data from the Zendesk knowledge-base to Salesforce Knowledge. Why do you need a connector over manually transferring data from Zendesk to Salesforce? The manual ETL process to move data is complex and would take a few weeks to a few months (depending on the amount of data). The connector, however, reduces that timespan to a few days. By establishing a thorough connection between both the knowledge bases, you can be assured of hassle-free synchronization of data. You save time and manual efforts and data management becomes impressively easy as well.
