What to do if you see the message "An error occurred in Xero. Check their API Status page."

The cause:

There is a technical issue on Xero's side, so any exports will temporarily fail.

The solution:

This is usually resolved by Xero within a day or so, so feel free to just wait a bit before trying to export again. You can also keep an eye on Xero's API status page for updates and/or reach out to their team.
