Technical specifications

Zalo Notification Service (ZNS) supports MSISDN (phone numbers). The Infobip standalone Zalo API enables you to use ZNS to send notifications to Zalo phone numbers. The connection to Infobip services uses firewalled in-house servers or API connections.

Zalo technical specifications

The advantage of using Zalo over API is that it enables you to have a failover in place if Zalo messages do not reach your customers. You can set up SMS as a fallback option to make sure that important communications are delivered to your customers if the customers are not connected to the internet or do not have the Zalo app installed.
