I've only just begun looking at development of Rdio apps and such, but every tutorial I have looked at asks to replace
script src="https://www.rdio.com/api/api.js?client_id='myidhere'
I have been trying to figure out how to get the ID for my application, but I am unable to find it. How do I get it?
That's the beta JavaScript API, you'll have to apply for an API key during the beta period.
