Which messaging channel has over 1 billion users in 190+ Countries and is one of the top 10 downloaded apps of all time? If you guessed Viber – you’re right! Here, we’ll explain more about the Viber Business API, as well as its advantages and limitations.

The Basics of Viber Business API

Viber Business API is an interface that allows a business to communicate directly with its audience through Viber. Businesses are able to personally interact with customers and keep them engaged to drive performance and encourage specific actions. It’s free to set up but does include monthly fees and messaging fees. A Viber chat can support:

  • Text

  • Images

  • Videos

  • Buttons

  • Links

  • Files

  • Two-way conversation between brand and customer

  • …and more all in the same message.

Additional features:

  • Ability to implement a chatbot, community, stickers, and advertising.

Viber Business Messages takes the best of both worlds from RCS and WhatsApp: in addition to the reach and popularity of the Viber app. We’ll go into more of the benefits below.

Multiple Forms of Communication

A business can choose between a one-way or two-way messaging. Each kind requires a different integration. One-way messaging delivers direct messages to customers without them being able to reply. Two-way messages create a dialogue between a brand and customers, allowing both parties to send and receive messages in a conversation.

Types of Messages

There are two types of messages that can be sent with Viber Business API: promotional messages and transactional messages.

Promotional Messages

A promotional business message is a message that contains information that promotes a business’s products or services, offers a discount, or provides commercial information. This message may include a button, emoji, image, video, and more.

Transactional Messages

A transactional business message is a message that contains text only, though it may also contain a URL.

Business messages that are not transactional and/or targeted to a specific user will be considered and charged as a promotional message. When a first message is sent from a business to a user it must be a personal, informative, and a targeted message - not a promotional one.
