If your app uses React Native, Ionic, Android, or another framework with a WebView component, you can integrate by pointing it at the widget’s hosted page instead of embedding the web component directly.
Use this method only inside a WebView. Loading it in a regular mobile browser is a security risk: the full URL, including the session token, can end up in browser history and be visible to anyone with access to the device.
Pass the token and any other setting as query parameters — see Passing parameters in the URL:
React Native example
Other frameworks
Font customization is done through the CSS custom property --ripio-font-family, not through a URL parameter — see Theming.
