Data structures

This document contains a reference of data structures available in the Agent Chat API. Here, you can review the object fields, as well as sample responses for the event, user, and other common structures. The reference applies both to the Web and RTM APIs.

Events

One of the data structures are events. They are sent to a chat via the send_event method. Apart from events, there are also Properties, Users, and Other common data structures. These are the available event types:

Form

The Form event contains an empty form to be filled out by the customer. It doesn’t matter how the form is configured or what fields it has — it can be any event of type form. Currently, the Form events are not supported natively in Text, but you can leverage this feature in a custom chatting solution. Request

`form_id`	always
`form_type`	optionally	The most popular form types include: `prechat`, `postchat`, `ask_for_email`, but those aren’t the only possible options. If you don’t see this field in a chat, it means that chat had been started before we introduced this field.

`deleted`	optionally	Appears for deleted events, visible only to users with the `administrator` or `viceowner` role.

A sample use case: sending a form in the chat after a pre-determined agent’s inactivity period. This could be a way of gathering contact info from customers so that the overloaded agent can contact them later.
