Soundcloud API (PHP SDK) CLIENT_ID Validation
===

I am trying to access the Soundcloud API with PHP to access user details.
I have obtained a soundcloud CLIENT_ID by activating my app through my personal soundcloud account, but it doesn't seem to work when accessing other public users information.

Here are my questions :

**Does the CLIENT_ID change per user?**

**Does the app need to be validated/accepted by every user in order to access information such as song list, etc... ?**

Currently there will only be `GET` requests, but in the future id like to work with `PUT` and such.

Please explain how the API is access with each type of request.

This is probably a very simple answer, but I need insight into the fundamentals of the API, so I can get the ball rolling.

Thank you.
