# Web SDK

> **Warning**
>
> Ada has deprecated Chat. Messaging fully replaces Chat on December 15, 2026. Read [Introducing Messaging](https://docs.ada.cx/2026-09-30-introducing-messaging) to learn how to migrate.

This page covers the legacy Chat Web SDK. For Messaging, follow the [script tag migration](/messaging/web/getting-started#migrate-from-the-chat-sdk-web-script) or [npm package migration](/messaging/web/getting-started#migrate-from-the-embed2-npm-package).

The Ada Web SDK makes it easy to embed Ada’s AI agent directly into your website or web application. It is designed for flexibility and customization, allowing you to programmatically manage key settings and actions to create a personalized user experience.

With the SDK, you can:

* Utilize event listeners to monitor key events such as when a new message is received, when an agent joins or leaves, and when a conversation ends.
* Customize the AI agent’s behavior by setting the initial language, defining greetings, and passing user-specific data through metaFields for personalized interactions.

## Resources

* To begin, check out the [Web SDK Quick Start Guide](/chat/web/getting-started).
* For detailed instructions, including customization and other settings, check out the [detailed instructions here](https://docs.ada.cx/docs/generative/deploy-ada-across-channels/chat/get-started-with-chat).
* For a comprehensive list of settings and actions, check out the [Web SDK Reference](/chat/web/sdk-api-reference).
