401 Unauthorized


#1

I try to build an Windows 8 app where I’ll integrate Twitter. So there is no callback URL.
After long search I’ve made it to obtain user token and secret. Now I try to get users timeline. But I always get 401 Unauthorized or in the response “Could not authenticate you” with error 32. I’ve used the OAuth Tool to generate Authorization header and Signature base string to compare it with the values I send. They looks pretty similar to me, except the nonce.

GET&https%3A%2F%2Fapi.twitter.com%2F1.1%2Fstatuses%2Fhome_timeline.json&oauth_consumer_key%3DGszx6r0cSieo3OwyH3SA%26oauth_nonce%3D4387f13969df533a0b0a294d9884506b%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1371117616%26oauth_token%3D1470508532-5JPWuH66asacc45qGkKKYuP50QEPOA55VrXfV9o%26oauth_version%3D1.0

Any ideas why it’s not working?
