IMPORTANT
You can send Viber bot messages only to users who have a valid [Viber bot user ID](https://www.infobip.com/docs/viber/bots#technical-specifications). These IDs are captured when users interact with your bot and stored in [People](https://www.infobip.com/docs/people). To use [Broadcast](https://www.infobip.com/docs/broadcast), your audience must include profiles from People or imported contacts that contain valid **Viber bot user IDs**.

## Viber Bots over Answers

Use Viber Bots over the Infobip chatbot building platform, [Answers](https://www.infobip.com/docs/answers), to build artificial intelligence and keyword-based custom chatbots with automated responses. Use these chatbots as the first point of contact for customers to get answers to a predefined set of queries at any time.

## Viber Bots over Conversations

Use Viber Bots over the Infobip cloud contact center solution, [Conversations](https://www.infobip.com/docs/conversations), to provide customers with real-time support through one-on-one conversation with an agent.
