Help with Webhook from Google App Scripts

I have never created a Webhook in Zapier and I’m not sure what I’m doing wrong. 

Does anyone have an example of a Webhook that is running from a Google Apps Script?
I want to run a function that adds a new row at the top to a sheet . . . when a row is added in a different sheet.
 

I am adding a new row in sheet ‘rawdata’ via Zapier and when that row is added, I want to run the below function to copy that row to the top of another sheet ‘New Order’.
I’ve tried get and post . . . I’m not getting errors now . . but it isn’t doing anything either.

I’m attaching a copy of the webhook in Zapier.  

Any help would be appreciated.
Thanks,

Jan

Function:

function rawDataNewRowToNewOrdersSecondRow() {

  const targetRow = 2;

  let S = SpreadsheetApp.getActiveSpreadsheet();

  let R = S.getSheetByName("rawdata")    //.getRange(2,1,S.getSheetByName("rawdata").getLastRow()-1,14).getValues();

  let rawDataRange = R.getDataRange();

  let rawDataValues = rawDataRange.getValues();

  let rawDataLastRow = rawDataRange.getLastRow();

  let rawDataLastRowValues = R.getRange(rawDataLastRow, 1, 1, 14).getValues();

  let rawDataRowCount = rawDataValues.length;

  let rawDataColumnCount = rawDataValues[0].length;

  let newOrdersSheet = S.getSheetByName('NEW ORDERS');

  let newOrdersRange = newOrdersSheet.getDataRange();

  //let newOrdersRange = newOrdersSheet.getRange(1,1,rawDataRowCount,rawDataColumnCount);

  let newOrdersLastRow = newOrdersRange.getLastRow();

  newOrdersSheet.insertRowBefore(targetRow);

  newOrdersSheet.getRange(targetRow, 1, 1, 14).setValues(rawDataLastRowValues)

}
