Trigger Flow Sync Not Firing

When a Trigger Flow appears to be configured correctly but no sync events appear in your SmartSyncApp dashboard, it indicates a disconnection somewhere in the event pipeline. This guide provides a systematic approach to diagnose and resolve the issue.

Step 1: Verify You Are Editing the Correct Column

The most common cause is editing a column that is not the monitored column. Trigger Flow only fires when the specific column you selected during setup is modified. Double-check in your flow configuration which exact column is being monitored. A common mistake is editing "Status Notes" when the flow is configured to monitor "Status".

Step 2: Check Condition Logic

If you have configured conditional triggers (e.g., "Only sync when Status = Approved"), ensure your test edit satisfies the condition. If you change Status to "In Progress" but the condition requires "Approved", the sync will correctly not fire. Check your condition configuration in the SmartSyncApp dashboard.

Step 3: Confirm Webhook Registration

Navigate to your flow's detail page in SmartSyncApp and verify the webhook status:

• Active: The webhook is registered and should be receiving events. Proceed to Step 4.
• Disabled/Expired: Click "Re-activate" to register a new webhook. Webhooks can expire if the Smartsheet account owner's permissions have changed.
• Error: The webhook registration failed. This typically means the Smartsheet API token has been revoked. Re-authorize your Smartsheet connection.

Step 4: Re-Authorize the Smartsheet Connection

If the Smartsheet account owner has changed their password, revoked API access, or if the OAuth2 token has expired (typically after 90 days of inactivity), the integration will silently fail. Go to SmartSyncApp Settings → Connections → Smartsheet and click "Re-authorize".

Step 5: Test with a Known-Good Edit

After completing the above steps, make a simple, unambiguous test edit: change a cell in the monitored column to a value that satisfies your conditions. Confirm the sync event appears in the dashboard within 60 seconds.
