How to send message to not subscribed user in Viber

Question

Is this possible to send message via Viber Api to not subscribed user by means of Viber Bot. I can't find any info on that in docs: https://developers.viber.com/docs/api/rest-bot-api/#send-message . But i constantly receive message from companies i've never subscribed to, so it seems feasible

Answer 1

You need to use Viber Business Messages instead. Because Viber Bot API is for another purpose.

For that, you need to use one of Viber Messaging Partners and use their API (not Viber) to send messages. Then you'll be able to send promotional and transactional messages to your auditory.
