The Concur integration runs on the Travel Inbox.
Just setup a daily Concur report with the travel and expenses you want to capture and add [email protected] as a recipient. EventGeek will automatically add the travel and expenses to the right Event.
Note that any users in the Concur report must also be an Org Member in EventGeek. However, they can be a No Access Member, meaning that they won't have login access or receive email from EventGeek.
