If you find that your integration with your cloud accounting software has expired, you don’t need to worry: integrations expire once a year and you will be notified when this happens.
All needed is to refresh your integration with your cloud accounting software package:
1. Head to the 'Account Settings' menu and open the 'Integration' tab.
2. Click ‘Change’ next to ‘Current integration’ and select your accounting software again.
3. Although the error messages may still appear, you can try to publish your items now
