I\'ve been trying to recreate the spotify oauth connection in MeteorJS. I\'ve gotten as far as requesting the access and refresh tokens, but I keep getting a 415 error now.
If youre doing this clientside its not working because you're not allowed to post to another domain from the client side because of the same origin policy.
If this is server-side I'd recommend using a pre-existing spotify api npm module instead of writing your own requests. There are plenty of spotify api implementations on npmjs.org.
Use arunoda's npm package for integrating npm packages in your meteor application
