UnityWebRequest, C# request.accept equivalent?

Hello, I have tried searching for this question but I either cannot word it properly, or I just don't understand it enough to know what to look for.

I am trying to send a UnityWebRequest, but I need to specify the data type to accept from the API. In standard C# it would look like this:

 public class MainClass {
   public static void Main (string[] args) {
     var request = (HttpWebRequest)WebRequest.Create("https://www.website.com/apistuff");
     request.Method = "GET";
     request.Headers["Authorization"] = "Bearer <TOKEN>";
     request.Accept = "application/json";
 
     var response = (HttpWebResponse)request.GetResponse();
 
     Console.WriteLine (response.StatusCode);
     var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
     Console.WriteLine (responseString);
   }
 }


  

So far, I think I know how to assign the Header properly using the UnityWebRequest.SetHeader(name,value) method. What I'm missing is the Unity equivalent to the standard C# request.Accept to make sure that I get the correct data type. Basically, what I have in the code for Unity is this:

 IEnumerator GetData()
     {
         Button1.text = "Loading...";
         string uri = "https://website.com/api";
         using (UnityWebRequest request = UnityWebRequest.Get(uri))
         {
             request.SetRequestHeader("Authorization", "Bearer " + APIKey);
             yield return request.SendWebRequest();
             if ((request.isNetworkError) || (request.isHttpError))
             {
                 Button.text = "Error!";
                 Debug.Log("Request Error:" + request.error);
             }
             else
             {
                 if (request.isDone)
                 {
                     var quote = JsonConvert.DeserializeObject<Response>(request.downloadHandler.text);    //This fits the Json data to a preset model
                     if (request.downloadHandler.text != null && request.downloadHandler.text != "")
                     {
                         Response = request.downloadHandler.text;
                     }
                 }
             }
         }
     }


  

Any help at all would be wonderfully accepted, thank you for your time.
