Send a Viber Session

Sessions is a conversation flow that allows you to communicate with your clients in a defined time frame. Mainly to be used for customer support purposes, sessions open up a new channel of communication between you and your clients.

The session rate is applied ONLY if your client initiates the conversation. If a client sends a message and it turns into a session (due to the development of a conversation), the session starts from the first reply by a client to you.

You’re billed per session and not per each delivered message. This allows you to send and receive multiple messages at a fixed per-session price.

Each session is configured as follows:
• The session is set to a default period of 24 hours.
• Up to 60 messages can be sent in a single session by the business account. After 60 messages have been sent, a new session begins automatically.
• A fixed rate is set according to the message type.
• Clients can send up to 5 messages in a row without a user’s reply. The next message in a session can only be sent after the user response.

Session messages can be only of specific types:
• Text-Only
• Image
• File
