Product deprecation notice

Effective April 30th, 2026, the messaging functionality of the Vonage Conversation API will be discontinued. Access for new users will be closed, and messaging capabilities will no longer be available to existing users after this date.

The voice functionality of the Conversation API will remain available and is not impacted by this change. If you have any questions regarding this partial discontinuation, please contact your account manager or our support team.

A User is an object that identifies a unique Vonage user in the context of a Vonage Application. Vonage enables these User instances to communicate with one another. A User typically has a 1-to-1 mapping with a user in your application’s user database.

A person who will communicate via a Conversation must first have a User object created. A User can be thought of as an endpoint for communication. When the User object is created it is assigned a unique user ID.

A User is added to a Conversation through a Member object. A User can be a Member in multiple Conversations. A User can also have multiple Member objects in a single Conversation, each Member having a Channel associated with it. For example a User may connect to a Conversation through an App, Voice and SMS where those Channels are available to the User.
