I am currently exploring the best practices for seamlessly embedding custom external web applications into our Dynamics 365 portal pages. For a recent customer-engagement project, we developed a Destiny matrix calculator free to process user inputs and generate personalized data reports. Has anyone here successfully used IFrames or custom Liquid templates to integrate similar interactive tools without breaking the portal's responsive layout? Any advice on maintaining a smooth user experience between the external tool and the CRM would be highly appreciated.
