DeleteFunction

You cannot delete a function if it's associated with a cache behavior. First, update your distributions to remove the function association from all cache behaviors, then delete the function.

To delete a function, you must provide the function's name and version (ETag value). To get these values, you can use ListFunctions and DescribeFunction.
