title: Power Query, make http POST request with form data
body: <p>I have a REST API, which accepts only POST requests with form data.</p>
  
  <p>I know that in Power Query JSON requests are like this:</p>
  
  <pre><code>let
      url = "https://example.com",
      body = "{ ""first_param"": ""AAAAA"",  ""second_param"": ""BBBBBB""}",    
  
      Source = Json.Document(Web.Contents(url,[ Headers = [#"Content-Type"="application/json"], Content = Text.ToBinary(body) ] ))
  in
      Source
  </code></pre>
  
  <p>How it is possible to send form data??</p>
