title: Create HTTP GET Header Request
body: <p>I am using php and I want to create a HTTP request to access some API data. I have a document that says, I need to place the following request</p>
  
  <pre><code>GET /abc/api/Payment HTTP/1.1
  Content-Type: application/x-www-form-urlencoded
  X-PSK: [App Key]
  X-Stamp: [UTC Timestamp]
  X-Signature: [HMACSHA256 base 64 string]
  
  Body:
  var1, var1
  </code></pre>
  
  <p>I have app key, I can get UTC Timestamp and I can create signature. I am not sure how to start creating this request? I am using codeingiter. If someone can help with example to set the header and body?</p>
  
  <p>I also tried this url <a href="https://www.hurl.it/" rel="nofollow">https://www.hurl.it/</a> to place requests but can't make it work. Any suggestions?</p>
