On September 16, 2011, Damon Billian discussed how many users were unaware of CloudFlare's API despite its documentation in the forums. He provided a "cheat sheet" for frequently used features such as Development Mode, purging cache, pulling basic statistics, reporting spam, and updating screen captures. To use these features, users need their API key, zone ID, and account email address. The specific calls and parameters can be found in the CloudFlare Client Interface API.
