    The PAR Punchh Online Ordering and SSO API lets online ordering platforms
    authenticate guests (SSO), create loyalty check-ins for online orders, and

    Calls are signed with an HMAC-SHA256 `x-pch-digest` header and use a
    Bearer access token. Base URLs are provided by a Punchh representative.
