WebView enables you to add custom UI elements (using HTML, CSS, and JavaScript) into your chatbot. To use this feature, create your custom UI components with the necessary HTML code. Collaborate with the platform team to deploy your code on Yellow's Bitbucket repository. Once deployed, the platform team will host your code on Yellow's CDN, generating a unique URL. This URL can then be integrated into the WebView node of your chatbot.

You can preview the WebView in the WebView node. However, if the URL is invalid or restricted due to Content Security Policy (CSP), please contact our support team for assistance.
