        **Message Size Limitation:**


        When sending outbound messages via our API service, please ensure that
        the total message size remains below the channel's maximum size limit.
        API requests containing media or multiple media files exceeding this
        limit will result in an error.  

        For WhatsApp messages, the maximum size limit is 100MB.
