Viber Transactional & OTP Message Templates

From July 1, 2026, templates are mandatory for all Transactional Viber Business Messages.

This includes messages such as order confirmations, appointment reminders, and one-time passwords (OTPs), which will no longer support free-form text.

Transactional Message Templates are structured, text-only message formats that allow businesses to send standardized messages using dynamic parameters for personalization.

The Two Categories

Viber supports two types of transactional templates:

Part 1 — Creating a Template

Step 1 — Create the Template on Apifon's Platform

Templates are created through the Apifon platform, not via the API.

1. Go to mookee.apifon.com and log in.
2. In the left menu, click Templates.
    
   
3. Select the Viber Template tab.
   
   
   
   Here you can view, search, preview, delete, and check the status and ID of your templates.
   
   
   
   
4. Click the + Add button.
   
   
   
   
5. Select Transactional as the template type.
   
   
   
   
6. Choose either OTP or Transactional as the category. Each category has different requirements; for example, OTP templates require a single-use PIN.
   
   
   
   
7. Provide a descriptive name and language of your template.
   
   
   
   
8. Select Viber Sender ID from the dropdown. This must be one of your registered Viber senders. If no senders appear, you need to set up a Viber Sender ID first.
   
   

Step 2 — Define Your Parameters and Message Body

1. On the right side, under the message preview, click Add Variable. Enter a Variable name and an Example value, then click Add & Insert. You can add up to 5 variables.
   
   
   • Variable name — the placeholder name (e.g., NAME, ORDER). This is what goes inside  in the message body.
   • Example value — a sample value for preview purposes (e.g., Maria, A-4471).
     
      
     
     
2. In the center area, write your message body.
   
   
   
   
   Use the add variable button to insert variable names as  in the body of your message.
3. Follow all validation rules shown in the top-right of the template editor (character limits, formatting guidelines, etc.).
4. When ready, click Submit for Approval.

Step 3 — Track Approval and Get the Template ID

1. Back on the Templates menu, click the Transactional filter to see only your transactional templates.
2. Wait for Viber's review. The status updates automatically:
   
   

   Status	Meaning
   PENDING	Submitted, waiting on Viber's review
   APPROVED	Viber accepted the template
   DECLINED	Viber rejected the template. Create a new template with the required changes and resubmit it for approval.

3. Once APPROVED, you are ready to send.
