first of all i am quite knew at webservices and javascript.

I am trying to call a web service that returns a pdf file in this format :

In order to call the pdf i am using res.body just like the code below :

    var url="https://........../......./..../..";
    var options = {
  "rejectUnauthorized": false,
  "method": "GET",
  "url": url,
 "headers": {
    "Authorization": "Basic EJFHUygdiAISDGIF",
    "Content-Type": "application/json"
  }
 
};



request(options, (err, res) => {

  if (res.statusCode == 200 )  {
   
    conversation.logger().info("pdf:" + res.body); // in order to check the content of the pdf in the platform i use
  }
});

My problem here is that i dont know how to download or display the pdf content .

Any help would be valuable.
