Hi All, I found the Reference API with the Javascript tab here: [https://www.fmod.com/docs/2.02/api/studio-api-common.html](https://www.fmod.com/docs/2.02/api/studio-api-common.html) .  
Once I figured out how to download the Studio API here:  
[https://www.fmod.com/download#fmodengine](https://www.fmod.com/download#fmodengine)

I found the examples:  
/Users/MGW/…/testapp/fmodstudioapi20211html5/api/studio/examples

I popped the examples folder onto a webserver and tried to run them. The references to /public failed so I changed them to ./public sine the examples folder is not the web root.  
When I run them now, they find the assets in ./public, but all give this error:

Is there another module I’m missing ?  
Many thanks!

OK I found the issue. This gave me a clue:

Turns out FMOD requires HTTPS. Once I installed certbot and the letsencrypt cert on my web server everything works!

Many thanks for reading.
