      summary: Viber Send Bulk Messages API
      description: 'The Viber Send Bulk Messages API allows businesses to send campaign messages to multiple recipients at once. The recipients are defined by a `file_code` returned from the Campaign File Upload API.


        Supported bulk message types include text, image, text+image, text button, text button image, file, video, video+text, video+text+action button, and text template. Fallback delivery to SMS or WhatsApp is supported on any message type by including `fallback_channel` and the corresponding `fallback_sms` or `fallback_whatsapp` block inside the payload.


        Campaigns can be scheduled by providing `schedule_datetime` (format: `YYYY-MM-DD HH:MM:SS`) and `timezone` (e.g. `Asia/Kolkata`).'
