        We highly recommend utilizing our new Member Identity Provider to manage
        the standard OAuth flow, particularly for new integrations.

        For comprehensive technical details, please refer to the [Member
        Identity Provider docs](https://member-idp.developer.placewise.com/).

        The message may contain (depending on Loyalty Club configuration):


        * Generated password, valid for limited time, allows to sign in member -
        see: [OAuth Token > Create](api-3510810).

        * Login URL. Scheme of this URL is: `<login_url>?otp=<otp>`.
