Conversation API

The Conversation API is a low-level API that allows you to create various objects such as Users, Members, and Conversations.

Conversations are the fundamental concept the API revolves around. Conversations are containers of communications exchanged between two or more Users which could be a single interaction or the history of all interactions between them.

The API also allows you to create Events and Legs to enable text, voice and video communications between two Users and store them in Conversations.

Text, voice and video communications can currently flow through various Channels like App, Phone, SIP, and Websocket. To enable the App channel (for in-app messaging, voice and video), you would need to also utilize our Vonage Client SDK.

Phone, SIP and Websocket Channels are enabled through the Voice API and they all flow into Conversations.



This API is currently in Beta.

Vonage always welcomes your feedback. Your suggestions help us improve the product. If you do need help, please email and include Conversation API in the subject line. Please note that during the Beta period support times are limited to Monday to Friday.

Supported features

The Conversation API currently supports a range of communication channels described in this documentation.

As the Conversation API expands to support more and more Vonage services, the supported Channels will also expand. Conversations would, as a result, become the container for the history of all your communication exchanged via Vonage API Services. This history would then be accessible through the Conversation API.

IMPORTANT: If you are in APAC region there are some limitations. Please contact for information on how to obtain APAC LVN support via our Singapore servers.
