I use the JS-API and I access to the spreadsheet with the following script:
[script type="text/javascript" src="https://spreadsheets.google.com/feeds/cells/KEY/1/public/values?alt=json-in-script&callback=myCallback"][/script] note: (replace [ with <) Why this method works perfectly with a spreadsheet and returns me an error 400 for another spreadsheet? What causes this error?
