title: Call External API From Ruby on Rails Controller
body: <p>I am having difficulty calling an external API from my Ruby on Rails Controller</p>
  
  <p>The following code is my Destinations Controller</p>
  
  <pre><code>url = URI.parse("https://api.sygictravelapi.com/1.0/en/places/list?parents=#{@destination.destination_type.downcase}:#{@destination.sygia_id}&amp;level=poi")
  
  http = Net::HTTP.new(url.host, url.port)
  http.use_ssl = true
  
  
  req = Net::HTTP::Get.new(url.to_s)
  req.add_field 'x-api-key', ENV["SYGIC_API_KEY"]
  
  res = Net::HTTP.start(url.host, url.port) {
     |http|
     http.request(req)
  }
  </code></pre>
  
  <p>The problem is that when I make this request, the response is "Bad Request", without any further information. Using the exact same request headers and URL through Postman, I get a 200-OK response from the endpoint, plus the data I expect.</p>
  
  <p>When monitoring traffic using Wireshark, I see an HTTP request going to the API endpoint. But when using Postman, I see only TLS requests.</p>
  
  <p>I've also tried different encoding of the Query String parameters to no avail. My assumption is that it is one of these two things that is causing the issue: 1) SSL not being used 2) QueryString Parameters not attached to the HTTP request. But would like additional eyes on my code to check I'm not missing something obvious.     </p>
