Solution 1

Your solution to try and parse the answer (which is json) as string by yourself is a bad one...
Declare class with the structure of the answer:

C#

public class Result
{
  public string ApplicationID;
  public string CandidateName;
  // so on
}

Then use Json.NET[^] to parse it for you...

C#

Result res = JsonConvert.DeserializeObject<Result[]>(json);

JsonConvert.DeserializeObject
is not working.

You should use array type as JSON is returning an array.

Result res = JsonConvert.DeserializeObject<Result[]>(json);

Another thing you should follow the error message properly it may be case of you are provide wrong query string value with valid key.

That's is : Key :

token_transaction_no

but Value is : MobileNo
