I’m using the Zoom Layers API example.  
I cannot seem to load an ![]() tag, nor to connect to Firebase.  
It seems like it’s all blocked.  
What is the reason for this? Is it my servers fault maybe? Is it a Zoom limitation?

Thanks

Have you disclosed and justified the domains used by your images and scripts in your application settings under **Build your app** ; **Features** ; **Surface** ; **Domain Allow List**?

Hi @MultiplayerSession,

Do you mean under “Basic Information” → “OAuth Allow Lists”?  
If so then yes, I listed all the firebase related servers…  
gstatic,googleapis,firebaseio,[api.google.com](http://api.google.com)

When I access the website directly, I get an anonymous UID from Firebase Auth. When I activate the app on Zoom, if fails to communicate, must be blocked as you said, I just don’t know why…

Edit: Ok, now I’ve found the Domain Allow section, thanks!

Auth still cannot reach server

Ok, ended up adding https://YOUR\_PROJECT\_ID.cloudfunctions.net then it worked.  
THANKS!
