To embed a chat widget in Next.js or React, use a focused provider or widget pattern to configure the ChatKit UI by wiring your backend api.url, supplying a domainKey, and using a custom fetch to attach auth tokens.

Yes, you can route ChatKit frontend requests to a custom backend by configuring the api.url parameter and supplying a custom fetch function for secure authentication, rather than relying solely on hosted OpenAI workflows.

Secure authentication for a chat UI is handled by implementing a custom fetch function that attaches your auth token to requests, enforcing domain allowlisting and secure backend integration to protect your application.

Yes, ChatKit supports file uploads in vanilla JavaScript applications by configuring the upload handling settings within the UI widget, allowing users to securely submit files through the chat interface.

Domain allowlisting restricts chat widget requests to approved web domains, preventing unauthorized usage of your backend api.url and ensuring secure integration when deploying the UI across help centers, dashboards, or product sites.

The best way to configure a scalable chat UI is wiring the widget to a custom backend via api.url, enforcing domain allowlisting, and using custom fetch for auth token injection to manage secure, high-volume requests.
