XERO45 Sync Error in Xero Integration

If you see the error:

XERO45 Sync Error: Unable to sync Xero data due to an invalid authentication token. Please disconnect and reconnect Xero in the Workspace.

This means the authentication token connecting the Workspace to Xero has expired or is no longer valid.

Until the connection is refreshed, syncing and exports will fail.

Why the XERO45 Sync Error Happens in Xero

The XERO45 error typically occurs when:

• The Xero authentication token has expired.
• The Xero connection was revoked in Xero.
• The connected Xero account credentials were changed.
• The Xero admin user who authorized the connection no longer has access.

When the token is invalid, the Workspace cannot access Xero data.

This is a connection issue, not an export mapping issue.
