title: Get API endpoints/schema/parameters without Documentation
body: <p>This question has been asked before, but all of the answers were incomplete or negative.</p>
  
  <p>Although in none of them anyone said that they already have access to the API, which I do.</p>
  
  <p>I got my token and a few endpoints from the developer tools in Chrome and managed to make some successful calls (guessing/trial and error).</p>
  
  <p>There is no documentation for the API and nothing can't be found over the internet or on websites with public API's (it hasn't been created yet).</p>
  
  <p>I am using cURL in PHP to make the calls and I have tried all sorts of calls to get some positive responses, but I only get errors like Forbidden/Not allowed. (Also tried with Postman - but I have almost no experience with it)</p>
  
  <p>So, my question is: Is there any way to fetch the endpoints or somehow get a list of them? I'm not very familiar with API but having access already I think there must be a possibility, like pinging the address somehow and get them in response (more like a sitemap.xml)</p>
  
  <p><strong>Edit</strong>: Added some code I'm currently using</p>
  
  <pre><code>$header = array();
  $header[] = "token: ##########################";
  $header[] = 'Content-Type: application/json';
  $state_ch = curl_init();
  curl_setopt($state_ch, CURLOPT_URL,"https://api.domain.com/v3/messages.php");
  curl_setopt($state_ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($state_ch, CURLOPT_HTTPHEADER, $header);
  $data = curl_exec ($state_ch);
  </code></pre>
