ConversationBuilder

interface ConversationBuilder

A Conversation Builder represents a conversation that is about to be created, fetched, or updated. You can use this object to set up or modify a conversation before showing it.

Note: any changes you make here will not be sent to TalkJS immediately. Instead, instantiate a TalkJS UI using methods such as Session.createInbox.
