The encapsulation of a user interface within a chat session may be provided by dynamically creating the user interface within the chat session. The creation of a user interface within a chat session may be supported by determining that the user interface is to be created within the chat session and propagating, toward a device supporting the chat session, information configured for use by the device to create the user interface within the chat session. The creation of a user interface within a chat session may be supported by receiving information configured for use by a device to create the user interface within the chat session and initiating creation of the user interface within the chat session based on the information configured for use by the device to create the user interface within the chat session.
