  description: >-
    HTTP Basic authentication using your Sift REST API key as the username and an
    empty password (Authorization: Basic base64(api_key + ":")). The ingestion
    APIs (Events, Score, Labels) also accept the key as `$api_key` in the JSON
    request body. Account-scoped APIs (Decisions, Workflows, PSP Merchant
    Management) additionally require your numeric Account ID in the URL path.
    Mobile SDKs authenticate separately with a Beacon Key. There is no OAuth.
