Google Adwords API call to download data through C#

Question

I am working on some C# project to make API calls to Adwords to download data.

I have already get the access token by using:

WebRequest webRequest = HttpWebRequest.Create("https://www.google.com/accounts/ClientLogin");
        webRequest.Method = "POST";
        webRequest.ContentType = "application/x-www-form-urlencoded";

        string postParams =

            "accountType=" + HttpUtility.UrlEncode("GOOGLE") +
            "&Email=" + HttpUtility.UrlEncode("[email protected]") +
            "&Passwd=" + HttpUtility.UrlEncode("xxxx") +
            "&service=" + HttpUtility.UrlEncode("adwords") +
            "&source=" + HttpUtility.UrlEncode(string.Format("{0}-{1}-{2}", "sample1",
                "sample2", "1"));

        byte[] postBytes = Encoding.UTF8.GetBytes(postParams);
        webRequest.ContentLength = postBytes.Length;

        using (Stream strmReq = webRequest.GetRequestStream())
        {
            strmReq.Write(postBytes, 0, postBytes.Length);
        }

        string retVal = "";
        try
        {
            WebResponse response = webRequest.GetResponse();

            using (StreamReader reader = new StreamReader(response.GetResponseStream()))
            {
                string sResponse = reader.ReadToEnd();
                string[] splits = sResponse.Split('\n');
                foreach (string split in splits)
                {
                    string[] subsplits = split.Split('=');
                    if (subsplits.Length >= 2 && subsplits[0] == "Auth")
                    {
                        retVal = subsplits[1];
                    }
                }
            }
        }
        catch (WebException ex)
        {
            throw new ApplicationException("Could not generate auth token.", ex);
        }

I would appreciate if someone can let me know what is the next step to make an API call to download data. https://developers.google.com/adwords/api/docs/guides/reporting

Thanks.

Have you tried using the client library? code.google.com/p/google-api-adwords-dotnet — Jon Skeet

In addition to what @Jon mentions about using the client library, you should also check out the examples directory of the download, specifically the reporting example, and also the XML Schema for the report definition to modify the example for your specific requirements.
