I am using c# code to use api, it works fine when I don't add comma(,) but with comma it return unauthorized, Is there any issue with encoding of comma?
url
header parameter
basestringParameters.Add("track", "twitter"); basestringParameters.Add("locations", "-122.75,36.8,-121.75,37.8");
my base String
GET&https%3A%2F%2Fstream.twitter.com%2F1.1%2Fstatuses%2Ffilter.json&locations%3D-122.75%2C36.8%2C-121.75%2C37.8%26oauth_consumer_key%3DxtOm0eNd8pm7hv643YqjZKhjH%26oauth_nonce%3DNjM1NjgxMzQ2Nzk5MjAwOTc0%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1432519880%26oauth_token%3D603356335-N3LRAKyYobdbNB4PeMaQkjNsiHvEEcX9DKHiC93Q%26oauth_version%3D1.0%26track%3Dtwitter

Thanks!
twythonand more simply with the test feature that twitter provides at their webpage. You must have something wrong in the way you build your authorization. Please share some code. (I know it looks weird that your auth works when you don't include locations but rest assured this is not the problem. Just post code so that somebody can help) – lrnzcig
