    <p>I'm trying to post a Twitter status update and I just can't get it working.</p> <pre><code>var consumer = new TwitterConsumer(); // WebConsumer implementation var httpClient = new HttpClient(consumer.CreateAuthorizingHandler("THE_TOKEN", new HttpClientHandler())); var content = new FormUrlEncodedContent(new Dictionary&lt;string, string&gt; { {"status", "test"} }); // yes, yes, ugly code, only testing here var s = httpClient.PostAsync("https://api.twitter.com/1.1/statuses/update.json", content); var t = s.Result; var u = t.Content.ReadAsStringAsync().Result; // HTTP 401, response from Twitter is {"errors":[{"message":"Could not authenticate you","code":32}]} </code></pre> <p>Of course, initially I thought there were some problems with my auth tokens or the OAuth process, but all other things are working fine:</p> <p>The OAuth authentication seems to work, because I can access other API methods like <code>https://api.twitter.com/1.1/account/settings.json</code>.</p> <p><strong>I can even post status updates when submitting the <code>status</code> via the URI</strong>, like <code>POST https://api.twitter.com/1.1/statuses/update.json?status=test</code>. I only get the error when I try to put the <code>status</code> in the request body.</p> <p>According to Google a lot of people have similar problems, unfortunately the suggested solutions (like double-checking the url-encoding or the <code>content</code>-Request-Header) do not work for me (the request looks as it should in Fiddler).</p>

    1. COhttps://api.twitter.com/1.1/statuses/update.json accepts POST method only, so I am not sure you can submit status updates via GET method.

    2. COCompare the HTTP "Authorization" request header from account/settings.json API method with the "Authorization" HTTP request header from statuses/update.json and check for "oauth_consumer_key", "oauth_signature_method", "oauth_nonce", "oauth_token", "oauth_signature", check the Content-Type header too, this may helps you finding the problem.

    3. COvzamanillo, GET method definitely works. I don't think that my problem is with the OAuth authentication, because every other method I tried on the API works fine. Just not the posting of a new status.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
