Re: [twitter-dev] Reg: unauthorirzed error while getting profile url

Hi Yaswath,

While you might have something else wrong additionally, I'll make a couple quick points:

a) the URL (and all REST resource URLs) should have a version: you want https://api.twitter.com/1/account/verify_credentials.xml -- if you don't put the version there, your code will stop working completely one day. Without a version there today, you'll get weird behavior.

b) Your OAuth query parameters includes an oauth_verifier -- you should only send this parameter to the oauth/access_token step and discard it -- by including it in the request here, you may be invalidating it.

If it's possible for you to use HTTP header-based OAuth, I would highly recommend favoring it over this query string approach -- header-based auth is generally easier to debug and easier to get right.

Finally, access tokens can be manually expired by the end-user at any time; they don't intrinsically have an expiration time though.

%3d</request>
 <error>Could not authenticate you.</error>

Can anyone help me in resolving this issue.

And is there any expiry of the access token that was obtained?

Thanks,
Yashwanth Konathala.
