Hi Troy,

thx for the guide.
I don’t understand how to preset a value in Step 2. I can only chose values from previouse actions/triggers. In this case that would be the Webhook trigger with no Data available.

Hi @Niklas 

Whatever app is triggering the Zap step 1 webhook, would need to provide the values as part of the data payload, which can then be used in the Zap filter step.

I think I found a way to do this but I need to update all the rows on the spreadsheet. There is a UPDATE MULTIPLE ROWS for Google Sheets but it requires a ROW NUMBER at the end. How do you tell the update all rows to actually update all rows? 

Is there a way you can put something in the ROW NUMBER field to tell it to update all rows?

Hi @smccarthy956 

The Zap action for GSheets Update Row(s) works with Line Items.

No.

Perhaps look into using the GSheets API.
