I recently wrote an AppsScript that sends an e-mail every time a new tweet is posted on a specified Twitter account and encouraged you to copy it and use it on your own. I run it in Google Spreadsheets every 5 minutes and after several weeks I started to receive error messages that the script exceeds a limit of 150 API calls per hour imposed by Twitter. The script always fetches the latest tweets from a Twitter account in one API call per a single run, thus according to my configuration settings it should make a maximum of 12 API calls per hour. Wonder what is wrong here?
