To authenticate an Oracle HCM Cloud connector  instance with SAP Open Connectors, you must use the Username and Password that you use to log in to Oracle.

You also must enter the zone variation of the base URL used to access Oracle as the Server URL. For example, if you access Oracle at a URL like https://adc3-zdff-fa-ext.oracledemos.com/main.html#!/main, then the Server URL is https://adc3-zdff-fa-ext.oracledemos.com.
