We have identified an issue where all Quickbooks Online integrations are experiencing problems. We have traced the issue to a compatibility issue with the SDK version Cloud Elements uses and the current Quickbooks Online server configuration. We are working to have the fix pushed to our production environment later today (Dec 10, 2017).
