https://apis.rmlconnect.net/vbs/api/v3/send_bulk

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).
