Google Sheets live sync

Hi!

I am trying to set up a live sync between Google sheets and my Monday boards that updates with any new changes to rows or added columns. I have tested a few different third party apps but would really prefer to use Apps Script. I’ve uploaded the data and matched the headers but I keep getting an error on “var response = UrlFetchApp.fetch(url, options);”

I’m pretty new to this, so if anyone is able to take a look and help guide me it would be much appreciated! I’ve included screenshots.



Thanks!
