Xero Integration Error ยท Third-Party App Sync Failed

How to Fix Xero Integration Errors

A third-party app connected to Xero stops syncing -- displaying errors like "Integration failed to sync", "Authentication error", or "Cannot connect to Xero" in the third-party application.

At QuickFix Bookkeeping, Xero integration errors almost always trace to one of three causes: the Xero OAuth token expired (most common -- Xero tokens expire after 30-60 days of inactivity), Xero API rate limit hit, or the connected app's permissions were revoked in Xero.

Three Causes -- Which Applies?

OAuth Token Expired

Most common. The app shows "Authentication error" or "Reconnect required." Fix: disconnect and reconnect the app to Xero to generate a fresh token.

API Rate Limit

Xero allows 60 API calls per minute. If the app syncs too frequently, it hits the limit and pauses. Fix: wait 5 minutes and retry, or reduce the sync frequency in the app settings.

Permissions Revoked

Someone removed the app's access in Xero. Fix: Xero and gt; Settings and gt; Connected Apps and gt; re-authorise the app.

How to Fix Xero Integration Errors

METHOD 1Disconnect and Reconnect the App to XeroFixes expired token and permission issues
1

In Xero: Settings and gt; Connected Apps and gt; find the integration and gt; Disconnect. Wait 2 minutes.

2

In the third-party app: go to the Xero connection settings and gt; click Connect to Xero and gt; log into Xero when prompted and gt; grant the requested permissions and gt; complete the OAuth flow. The app receives a fresh token and syncing resumes.

METHOD 2Check Xero API Status + Reduce Sync FrequencyRate limit or Xero service issue
1

Check status.xero.com for active API outages. If clear: in the third-party app settings and gt; reduce the sync frequency from every 5 minutes to every 30 minutes or hourly and gt; retry a manual sync. Xero's 60 calls per minute limit resets every 60 seconds -- waiting resolves rate limit errors automatically.

METHOD 3Check Xero Organisation PermissionsApp connected but cannot access data
1

Xero and gt; Settings and gt; Users and gt; confirm the user who authorised the integration still has the correct role (Standard or Adviser). If their role was downgraded: the integration loses access to the data it previously had. Reconnect the integration using an Adviser-level account to restore full access.
