The user who clicks the Create Salesforce Token button is under whose authority Scheduled Conga Batch will operate. The Salesforce Token for Conga Batch will be listed in Salesforce under that user’s My Settings → Personal → Advanced User Details → OAuth Connected Apps. If the user revokes the Salesforce Refresh Token (in Salesforce Setup, under OAuth Connected Apps), all scheduled Conga Batch records will cease to operate on a scheduled basis.
