Capture headers in browser Dev tools

Question

Hi,

I have an app authenticating using AAD App proxy. It sends a user's properties in headers to the backend application for authorization.
Is there a way to capture what it is being sent to the backend application using the browser dev tools?

Thanks,
Regards

Thank you for your post and I apologize for the delayed response!

Adding onto what @Cristian SPIRIDON mentioned, when it comes to capturing a browser trace using Dev Tools, you should be able to do this by following our Capture a browser trace for troubleshooting documentation.

Note: This'll only capture browser traffic.

If you'd like to capture HTTP traces you can also try Collecting a network trace with Fiddler.

If you have any other questions, please let me know.
Thank you for your time and patience throughout this issue.

Hi @Youcef Tazairt ,

Azure AD Aplucation Proxy will handle only the communication between the Web app and your browser. You can see in the Web dev tools only that communication. If your Web app communicate with some APIs, then you need other means to see that.

Hope this helps!
