Overview: Chat UI API methods

An overview of Kustomer chat web SDK JavaScript API methods

Call the Kustomer.start() method to initialize Kustomer Chat. After you initialize chat, you can call and execute additional Web SDK JavaScript methods.

We've listed the available Web SDK methods below. Each entry provides a short description of what the method does and links to a page that provides syntax documentation and code samples for the individual method.

Initialize Kustomer Chat

Initializes the chat widget and renders the chat icon on your web page.


First, initialize chat fully

Kustomer Chat must finish initializing fully with Kustomer.start() before you can execute any additional Web SDK methods.

Tip: Call other methods inside the callback of Kustomer.start() to ensure Kustomer Chat always completes initialization before the code tries to run other methods.
