  notes: >-
    Wunderkind splits authentication by surface. Server-side APIs on
    api.wunderkind.co authenticate with a private API key sent as
    "Authorization: apikey {apikey}"; keys are created per API product
    (id-resolution, UCRM, ...) under Settings > API Credentials in Wunderkind
    Platform and require an Admin or Manager role. Client-side APIs on
    api.bounceexchange.com use a public key: the numeric website ID (site ID),
    normally supplied via the Mobile/Web SDKs. The Text Message API on
    api.wknd.ai uses paired X-Client-ID / X-Client-Secret headers provisioned
    by Wunderkind. The Email API documents Bearer (JWT) token authentication.
    A 400 error indicates an invalid or missing API key on server-side
    endpoints.
