Feature Flag
The HTTP API can only be used in a server environment.
You can use the HTTP API to check the results of feature flag distributions for users.
Authentication
Authentication is done through the SDK key. The SDK key must be sent in the HTTP header.
Depending on where you are calling the API from, set one of the Browser, App, or Server SDK keys in the header.
