Example datafile

The example shows what a datafile might contain. Use it to understand the configuration information that is passed in Optimizely Feature Experimentation.

The datafile is a JSON string that describes all the flag rules running in a given environment and dependent entities like audiences and attributes. Usually, you will not need to interact with the datafile directly. The SDK exposes methods that operate on it internally.
