OAuth Headers


I am trying to use the REST api, available through the “Test OAuth” link on my apps page in dev.twitter.com.
I can’t seem to get my keys to authenticate. I try generating an access token but I do not succeed. I try an example GET to /statuses/home_timeline, just to see one of the supposed high-uptime endpoints’ response. Still get json response of:

“errors”: [
“message”: “Could not authenticate you”,
“code”: 32

I have tried regenerating both my app and client keys but this still fails to authorize me.
How do I speak with support?
