title: Api-Version header is not sent correctly
body: <p>Dear friends I have a weird issue I try to connect to an API and when I try to do the API requests in postman or insomnia everything is okay. When I use the same code on my website and even on localhost the leads request doesn't work and tells me that api-version is not defined.</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"&gt;&lt;/script&gt;
  &lt;script&gt;
      var settings = {
          "async": true,
          "crossDomain": true,
          "url": "https://affiliate-api.tradingcrm.com:4477/token",
          "method": "POST",
          "data": "{ userName: \"alpt\", password: \"Alpt@12345\" }"
      }
  
      $.ajax(settings).done(function (response) {
          var settings2 = {
              "async": true,
              "crossDomain": true,
