Customize your Chatmode embed to match your brand and provide a seamless user experience. Customization involves configuring options in the Chatmode UI, potentially passing parameters during initialization, and applying custom CSS.

​
Configuring via Environment Settings (Chatmode UI)

Most visual and behavioral aspects of the chat interface inside the modal/iframe are configured within the Chatmode application when you set up your EMBED type Environment. Navigate to Environments -> [Your Embed Environment] -> Settings in Chatmode to configure:
  • Display Name: The text shown in the chat header.
  • Display Picture: The logo or avatar shown in the chat header.
  • Icon: The icon displayed on the floating chat bubble when closed.
  • Primary Color: Affects buttons and other accents within the chat interface.
  • Initial Message: The first message the Agent sends when the chat loads.
Changes made here automatically reflect in the embed.

​
Configuring via initBubble Options

The Chatmode.initBubble function, used in the standard Bubble Code snippet copied from the Chatmode UI, accepts a few client-side options to control the theme and custom icon: 
<script type="module">
  import Chatmode from "https://cdn.jsdelivr.net/npm/@chatmode/embed/+esm";

  Chatmode.initBubble({
    // Required - Copied from UI
    environmentId: "YOUR_ENVIRONMENT_ID",

    // Optional Configuration
    theme: "automatic", // "light", "dark", or "automatic" (default)

    // Optional - Pre-filled if icon uploaded in UI - Copied from UI
    // iconKey: "YOUR_ICON_KEY",
    // updatedAt: TIMESTAMP, // Cache-buster for icon
    position: "bottom-right", // "bottom-left" or "bottom-right" (default)
  });
</script>
  • environmentId (Required): Your specific Environment ID, obtained from the snippet copied in the Chatmode UI.
  • theme (Optional): Controls the color scheme (light, dark, or automatic based on user’s system preference). Defaults to automatic.
  • iconKey (Optional): The identifier for your custom icon uploaded in the Environment settings. This is usually pre-filled in the copied snippet if you uploaded an icon.
  • updatedAt (Optional): A timestamp used to prevent incorrect browser caching of the icon image. This is usually pre-filled along with iconKey.
Important: All other customizations, such as the chat header’s Display Name, Display Picture, the agent’s Initial Message, and the bubble’s main Icon and Primary Color, are configured exclusively within the Environment settings in the Chatmode UI. Note: Always start with the code snippet copied from the Chatmode UI, as it contains the required environmentId and potentially pre-filled iconKey and updatedAt.

​
Programmatic Control

When you initialize the bubble, you can optionally store the returned control object: 
const chat = Chatmode.initBubble({
  environmentId: "YOUR_ENVIRONMENT_ID",
  theme: "automatic",
  iconKey: "YOUR_ICON_KEY",
  updatedAt: TIMESTAMP,
  position: "bottom-right",
});

// Now you can use the 'chat' object:

// Open the chat modal
chat.open();

// Close the chat modal
chat.close();

// Toggle the modal
chat.toggle();

// Check if the modal is open
if (chat.isOpen()) {
  console.log("Chat is open");
}

// Remove the bubble and modal completely
// chat.remove();
This allows you to trigger chat actions from your own website’s code, for example, opening the chat when a user clicks a custom “Help” button.

​
Styling with CSS

CSS is primarily used if you opt for the Inline Embed method (using an <iframe> tag directly) rather than the standard floating bubble.

​
Styling the Inline Iframe Container

If you use the <iframe> code snippet (copied from the Environment settings as an alternative to the Bubble Code), apply standard CSS to the <iframe> tag itself to control its width, height, border, margin, position, etc., to integrate it seamlessly into your page layout. 
/* Example for an iframe with ID 'chatmode-inline-iframe' */
#chatmode-inline-iframe {
  width: 100%;
  max-width: 500px; /* Example constraint */
  height: 600px;
  border: 1px solid #eee;
  border-radius: 8px;
  margin: 20px 0;
}
While technically possible using browser developer tools to find CSS selectors and overriding them with !important, manually overriding the styles of the floating bubble (#chatmode-bubble-button) or its modal window (.chatmode-modal-container, etc.) is not recommended or supported. These internal structures may change without notice, breaking your custom styles. Stick to the customization options provided in the Environment settings (Display Name, Picture, Icon, Color, Initial Message) and the theme option in the initBubble script for the standard floating bubble.
