Viber template

To use Viber templates in BulkGate, first you need to have it approved for its content.

These changes are effective since 1st of July 2026 to reflect new approach by Viber. Older ways of sending template message will become deprecated.

To approve template you need to go into BulkGate portal. Navigate towards the left nav panel and click SMS & Viber messaging, then Viber Templates.

Sending template for approval

In order to have your Viber template approved you need to submit it into BulkGate portal. Template consists of key and name that can both be used to identify template. Input sender and select type of message that will determine whether it is template for transactional message, or an OTP message. And also body of a template which is text containing user defined variables.
