I'm trying to build something like heardle using the soundcloud api. I want to stream songs from soundcloud onto a web javascript application.

I've gone through the documentation and tried a bunch of example tutorials around the web and they all seem to not work. It seems that Soundcloud removed the ability to register new apps a couple years ago. It also seems that you can build a more basic app without app registration (I think?).

Every time I do the basic tutorials I've found around the web I get a 403 error (yes I am replacing the client ID with my own). Here are a couple examples:

I've searched around, but I'm not getting any good answers to what exactly the problem is. It seems Soundcloud has changed it's rules and apis enough that I'm not the only one confused. Is this still possible or am I just having some basic 403 issue?

Any help is deeply appreciated.
