This topic explains how to send Viber business messages using Chat App Message Service.
Before you begin
Apply for a Viber Service ID and get it approved by Viber.
Procedure
Log on to the Chat App Message Service console.
In the left navigation pane, choose Channel Management.
NoteIf you are a service provider, Channel Management appears as Customer Management in the navigation pane.
Click the Channel ID of the Viber channel you want to manage.

On the channel details page, choose Message Sending.
Set Language to specify the language of the message template.
Click Select Template to select a message template from the drop-down list.
NoteThe template list is filtered by your selected Language, showing only Viber templates in that language.
Select a Send Account (the Service ID linked to your channel).
Choose a Send Type:
Timing Send: Specify a future date and time to send the message.
Immediately: Send the message immediately after you click Send.
Select a Fallback Policy:
None: Do not use a fallback.
The drop-down list shows existing fallback policies.
NoteTo configure a fallback policy, you must first enable the Short Message Service (SMS) on the Service Settings page.
When a fallback policy is active, it is triggered if a message's delivery status is
undeliveredorsentFailed. Other failures, such as a deleted message template or invalid parameters, also trigger the fallback.
Select a method for adding recipients:
Upload Excel File: Recommended for sending messages to a large number of recipients. Click Download Template to get a sample file, fill it with recipient phone numbers, then click Upload File to upload it.
NoteThe Download Template button is disabled until you select a message template.
If your message template contains variables, you must use the Upload Excel File method to import recipients. Do not modify the column headers in the template file, or variable mapping will fail.
Import Phone Number Group: Recommended for sending messages to a small number of recipients. Click Add Phone Number to manually enter phone numbers.
Import Group: Recommended for messaging pre-defined audiences. To create a new group, choose Intelligent Marketing > User Group Management in the left navigation pane, then click Create Group.
Click Send. You can view the message sending details on the Message list page.
