VIBER + SMS API

DecisionTelecom Viber + SMS API allows you to send and receive Viber business messages to and from any country in the world via API, and if Viber message is not delivered to a client, it will be resend and delivered as regular SMS message. Each message is identified by a unique random ID, so users can always check the status of a message using given endpoint.

The Viber + SMS API uses HTTPS with access key that is used as the API authorization. Request and response payloads are formatted as JSON using UTF-8 encoding.

Please contact your account manager to get an API key.
