Viber recently opened up an interface for chat-bot automation. Claudia Bot Builder, since version 2.5.0, allows you to easily create and deploy chat bots for the new Viber platform. In this set-by-step tutorial, you’ll learn how to create a Viber chat-bot and deploy it to AWS Lambda.
- Node.js 8.10 with NPM (Node 6 is also supported by Lambda)
- An AWS account with the permissions to create Lambda functions, API Gateway end-points and IAM roles.
- Claudia.js 4.0.0 or later

Deploying your Viber bot
You can now deploy the bot to AWS:
bot.js, this will be just
While deploying, Claudia will ask for your Viber Public Account Access Token. It will then automatically create the right web hooks for the Viber bot platform. In a few moments, your bot will be online and you will be able to chat to it using Viber.
And that’s it.
