Hi Joshua,

code works perfect. But, how can I add geocode and unti parameters to your MakeTwitterCall function. These parameters are listed in this url: https://dev.twitter.com/docs/api/1.1/get/search/tweets

Many of these are working but when I add these two parameters in my IEnumerable<KeyValuePair<string, string>> RequestParameters then twitter send empty results.

Can you help me?
Thanks.

Guys plz I need ur help in this :

I am getting the same unauthorized like most people. After reading this, it is probably with my signature. I am trying to do a query using the geocode. here is my code:

var geocode = "42.791306,-86.033448,1mi";
        var baseFormat = "geocode={7}&oauth_consumer_key={0}&oauth_nonce={1}&oauth_signature_method={2}" +
                        "&oauth_timestamp={3}&oauth_token={4}&oauth_version={5}&q={6}";

        var baseString = string.Format(baseFormat,
                                    oauth_consumer_key,
                                    oauth_nonce,
                                    oauth_signature_method,
                                    oauth_timestamp,
                                    oauth_token,
                                    oauth_version,
                                    Uri.EscapeDataString(q),
                                    Uri.EscapeDataString(geocode)
                                    );

…

var postBody = “q=” + Uri.EscapeDataString(q) + “&geocode=” + Uri.EscapeDataString(geocode);
resource_url += “?” + postBody;

That all looks fine to me I haven’t tried using Geocode at all I can try and get code working for you tomorrow. I can’t promise anything though.

This worked for me you may have your tokens wrong.

hi Britney,
thanks for your code example, It has helped me a lot with my application but i still have a problem.
Im trying to use streaming API and send a POST in order to connect and read tweets to the public stream
https://stream.twitter.com/1.1/statuses/filter.json
I followed your example but i still receive Error 401 Unauthorized.

here my code:

        string URL = "https://stream.twitter.com/1.1/statuses/filter.json";
        string query = "track=twitter";

        // oauth application keys
        string oauth_token = "xxx";
        string oauth_token_secret = "xxx";

can you help me to find out what am I doing wrong?

I’m using this example to get the replies on a tweet but return json doesn’t include the replies at all.
https://dev.twitter.com/docs/api/1.1/get/statuses/home_timeline

Please help me on this. I’m using this url:
https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name=mujeebfarooqi&count=1&exclude_replies=false

Also, if I want to get the replies of a particular tweet then how i’ll do it?
like sample url: https://twitter.com/MujeebFarooqi/status/459340704356261888
