Google Drive insert file permission

I can't insert permission to a file with this code:
string URI = String.Format("https://www.googleapis.com/drive/v2/files/{0}/permissions&access_token={1}", fileId, "token");
var request = (HttpWebRequest)HttpWebRequest.Create(URI);
request.Method = "POST";
request.ContentType = "application/json";
string json = "{\"role\": \"reader\",\"type\": \"anyone\"}";
byte[] byteData = new System.Text.ASCIIEncoding().GetBytes(json);
request.ContentLength = byteData.Length;
using (var dataStream = request.GetRequestStream())
{
dataStream.Write(byteData, 0, byteData.Length);
}
var response = (HttpWebResponse)request.GetResponse();
using (var reader = new StreamReader(response.GetResponseStream()))
{
json = reader.ReadToEnd();
}
I al getting a 404 error. What's the problem?

string URI = String.Format("https://www.googleapis.com/drive/v2/files/{0}/permissions&access_token={1}", fileId, "token");
Access token is not a string "token" it must be a valid access token for the user who owns the file.
Update:
permissions?access_token={1}",
You should be using ? and not & to add a parameter to the url. Not even sure you can do it like that with a HTTP Post.
Added info:
If this is not simply a typo on your part you may want to read up on Authorization a little
I also recommend checking out the Google client library instead of writing this yourself. Google.Apis.Drive.v2 Client Library.
There is a newer version of the Google Drive API you might also be interested in looking at rather then writing new code for an older version of the API. Google Drive API v3.

Access JIRA API with C# using AccessToken

I have created AccessToken using https://developer.atlassian.com/display/JIRADEV/JIRA+REST+API+Example+-+OAuth+authentication tutorial and could connected and get the data from jar file. I need to access it with c# app. I tried following code but it wasn't working.
var request = (HttpWebRequest)WebRequest.Create(apiUrl);
request.Method = "GET";
request.Headers.Add("Authorization", "Bearer " + API_Access_Token);
var response = (HttpWebResponse)request.GetResponse();
string html = string.Empty;
using (StreamReader reader = new StreamReader(response.GetResponseStream()))
{
html = reader.ReadToEnd();
}
Original question was Access JIRA API with api key without username and password

How do I post to GitHub API v3

I am using GitHub API v3 with C#. I am able to get the access token and using that I am able to get the user information and repo info.
But when I try to create a new repo I am getting the error as Unauthorized.
I am using HttpWebRequest to post data, which can be seen below. Please suggest me some C# sample or sample code.
(..)string[] paramName, string[] paramVal, string json, string accessToken)
{
HttpWebRequest req = WebRequest.Create(new Uri(url)) as HttpWebRequest;
req.Method = "POST";
req.ContentType = "application/json";
StreamWriter writer = new StreamWriter(req.GetRequestStream());
writer.Write(json);
writer.Close();
string result = null;
using (HttpWebResponse resp = req.GetResponse() as HttpWebResponse)
{
StreamReader reader =
new StreamReader(resp.GetResponseStream());
result = reader.ReadToEnd();
}(..)
Note: I am not sure where i need to add the accesstoken. I have tried in headers as well as in the url, but none of them works.

Are you using the C# Github API example code? I would look at that code to see if it does what you need.

You can use basic auth pretty easily by just adding auth to the request headers:
request.Headers.Add("Authorization","Basic " + Convert.ToBase64String(new ASCIIEncoding().GetBytes(username +":"+password)));
Sorry havent used the access token stuff yet.

You need to add this token here:
req.UserAgent = "My App";
req.Headers.Add("Authorization", string.Format("Token {0}", "..token..");

Try
rec.Credentials = CredentialCache.DefaultCredentials;
or use non-default credentials.

HTTP Basic Auth for Diigo using C#: How to read response?

I am (trying) to develop a WPF (C#) app that just gets (or at least is supposed to get) my saved bookmarks at Diigo.com profile. The only helpful page i found is this . It says i have to use HTTP Basic authetication to get my self authenticated and make requests then. But don't understand how C# handles it!. The only solution i came up with below just prints entire HTML source to console window.
string url = "http://www.diigo.com/sign-in";
WebRequest myReq = WebRequest.Create(url);
string usernamePassword = "<username>:<password>";
CedentialCache mycache = new CredentialCache();
mycache.Add(new Uri(url), "Basic", new NetworkCredential("username", "password"));
myReq.Credentials = mycache;
myReq.Headers.Add("Authorization", "Basic " + Convert.ToBase64String(new ASCIIEncoding().GetBytes(usernamePassword)));
//Send and receive the response
WebResponse wr = myReq.GetResponse();
Stream receiveStream = wr.GetResponseStream();
StreamReader reader = new StreamReader(receiveStream, Encoding.UTF8);
string content = reader.ReadToEnd();
Console.Write(content);
Here username and password are hardcoded but of course they'll come from some txtUsername.Text thing. And after that how am i going to read the JSON response and parse it?
What is that i need to do to get my app or myself HTTP basic authenticated?
Any help or suggestion is welcome!

If you're trying to talk to a service, you probably want to use the Windows Communication Foundation (WCF). It's designed specifically to solve the problems associated with communicating with services, such as reading/writing XML and JSON, as well as negotiating transports mechanisms like HTTP.
Essentially, WCF will save you doing all of the "plumbing" work of working with HttpRequest objects and manipulating strings. Your problems have already been solved by this framework. Use it if you can.

Ok i solved the problem after some (not really some) effort. Code below gets the JSON response from server which can then be parsed using any preferred method.
string key = "diigo api key";
string username = "username";
string pass = "password";
string url = "https://secure.diigo.com/api/v2/";
string requestUrl = url + "bookmarks?key=" + key + "&user=" + username + "&count=5";
HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create(requestUrl);
string usernamePassword = username + ":" + pass;
myReq.Timeout = 20000;
myReq.UserAgent = "Sample VS2010";
//Use the CredentialCache so we can attach the authentication to the request
CredentialCache mycache = new CredentialCache();
//this perform Basic auth
mycache.Add(new Uri(requestUrl), "Basic", new NetworkCredential(username, pass));
myReq.Credentials = mycache;
myReq.Headers.Add("Authorization", "Basic " + Convert.ToBase64String(new ASCIIEncoding().GetBytes(usernamePassword)));
//Send and receive the response
WebResponse wr = myReq.GetResponse();
Stream receiveStream = wr.GetResponseStream();
StreamReader reader = new StreamReader(receiveStream, Encoding.UTF8);
string content = reader.ReadToEnd();
Console.Write(content);
content is the JSON response returned from server

Subscribe through API .net C#

I have to submit subscription data to another website. I have got documentation on how to use this API however i'm not 100% sure of how to set this up. I do have all the information needed, like username / passwords etc.
This is the API documentation:
https://www.apiemail.net/api/documentation/?SID=4
How would my request / post / whatever look like in C# .net (vs 2008) when i'm trying to acces this API?
This is what i have now, I think i'm not on the right track:
public static string GArequestResponseHelper(string url, string token, string username, string password)
{
HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(url);
myRequest.Headers.Add("Username: " + username);
myRequest.Headers.Add("Password: " + password);
HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse();
Stream responseBody = myResponse.GetResponseStream();
Encoding encode = System.Text.Encoding.GetEncoding("utf-8");
StreamReader readStream = new StreamReader(responseBody, encode);
//return string itself (easier to work with)
return readStream.ReadToEnd();
Hope someone knows how to set this up properly. Thx!

The documentation doesn't state clearly if the credentials should be passed as HTTP headers. They talk about parameters, so I would also try passing them as GET parameters:
url = string.Format("{0}?Username={1}&Password={2}", url, username, password);
HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(url);
