Contacts not uploading on pabbly chatflow through pabbly connect

Hi Deepak,

Thanks for reaching out about your Google Sheet to Pabbly Chatflow contact sync that worked initially but has now stopped, even though the connection shows success and new rows are being added.

When a Google Sheets trigger stops firing on new rows, it is usually a trigger configuration issue rather than the Upsert Contact step. Please check the following:

1. Open your Google Sheet, go to Extensions > Pabbly Connect Webhooks, and confirm the correct send mode is enabled:
   - Send on Event - use this if rows are added manually.
   - Auto-Send on Schedule - use this if rows are populated by a third-party application/integration (e.g. a form tool or another automation writing into the sheet). Manual Send on Event will not fire for third-party writes.
2. Make sure the trigger column (the final data column) is consistently filled, since Pabbly only fires when that column receives a value.
3. Verify the webhook URL in the Google Sheets extension still matches the trigger URL in your current workflow.

After adjusting this, add 2-3 new test rows and check the workflow's Task History to confirm they are being received. If the issue persists do let us know.
