As you might now I have just started working at a chatbot developer company and as preparation besides many other things I was reading through Viber's REST API documentation. I made some notes for myself and then I realized I could share them with you, maybe for some people it could be quite useful to have a summary.

Getting started

To be able to implement the API you need the followings:

• Active Viber Account
• Active Public account/ bot --> you can register one here
• Authentication key retrieved from your Public Account
• Account webhook

Example for Authentication key, which should be included in the HTTP Header of the requests:
X-Viber-Auth-Token: 445da6az1s345z78-dazcczb2542zv51a-e0vc5fva17480im9

Setting a webhook

Basic Text Message Example

Possible message types

• Picture
• Video
• File
• Contact
• Location (latitude, longitude)
• Url
• Sticker
• Carousel → side-scrollable multi-option panel
• Keyboard → multi-choice answer possibility

Broadcast message

Broadcast message allows you to send message to multiple receivers up to 300 people.
Change the key “receiver” to “broadcast_list” in the JSON:

Other basic API features

• Get user details
• Check if the user is online
• Post to public chat

Callbacks:

• Subscribe
• Unsubscribe
• Conversation started → response can be a welcome message
• Status (delivered/seen/failed)

Receive message from user

This was a brief summary of the API, I just wanted to list the key features and give some code examples. The whole, detailed description can be reached here:

Thanks for passing by!
