Hi.  
I have a private content access LMS platform – [studio.made2grow.de](http://studio.made2grow.de/). We are planning to add a web app (React app) hosted in HubSpot. Now, we are questioning ourselves about the authorization of the user between the [studio.made2grow.de](http://studio.made2grow.de/) and our application. Is it possible to authorize [studio.made2grow.de](http://studio.made2grow.de/) users in an embedded react app in [studio.made2grow.de](http://studio.made2grow.de/)? In order to clarify my question, I have attached a screenshot.

Yes, this is possible! If you aren’t already using CMS Enterprise, I highly recommend upgrading to it. You can use serverless functions to securely perform authentication and other API integration on the backend. This keeps your application secure and provides an extra layer of backend code. We are big fans of using React with HubSpot CMS and serverless functions.
