  notes: >-
    Sift authenticates every REST call with a per-account API key. For the Events, Score
    and Labels APIs the API key is passed in the JSON request body as `api_key`. For the
    Decisions, Workflow, Verification and other REST APIs the API key is supplied via HTTP
    Basic authentication (the key is the Basic-auth username, password left blank). Many
    endpoints additionally require the numeric `account_id`. Separate Sandbox and
    Production API keys are issued per account from the Sift Console.
