title: How to send a query to Azure Table REST API with Postman
body: <p>I'm trying to make a GET request to Azure Table REST API with Postman.
  I can make a working request with a C# program I found, but when I try to copy the same information into the Postman request it return the followign error:</p>
  
  <blockquote>
    <p>Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.</p>
  </blockquote>
  
  <p>With the C# program I generate my UTC time and my Authorization code. 
  The program will give me the following output:</p>
  
  <blockquote>
    <p>x-ms-date: Fri, 01 Nov 2019 10:13:26 GMT</p>
    
    <p>Authorization: SharedKeyLite username:e4IREMOVEDSOMELETTERST4Ag=</p>
    
    <p>Request URI: <a href="https://username.table.core.windows.net/MainTable(PartitionKey=" rel="nofollow noreferrer">https://username.table.core.windows.net/MainTable(PartitionKey=</a>'akey',RowKey='130')</p>
  </blockquote>
  
  <p>The generated output works in the C# program, because when I use:</p>
  
  <pre><code>    result = await Client.GetAsync(requestUri);
  </code></pre>
  
  <p>The result will give me the information of <em>(akey, 130)</em>.
  When I pass them into postman it will still give me an error.
  I <strong>do</strong> update the date in postman whenever I make a new authorized string.</p>
  
  <p>My postman setup is as follows:

  <p>I eventually want to make this request with the ESP32, so it might be a bit unrelated, but the ESP is giving me the same error. Any tips on setting the headers correct either for Postman or the ESP are appreciated.</p>
