Parse the JSON Response in Salesforce Apex -Part 1

In this post I'm going to explain how to create a Wrapper class to Parse the JSON Response in Apex which contains key and value pair in JSON.

JSON String:

{
 "status": "SUCCESS",
 "errors": [],
 "data": {
  "oldCaseStatus": "Case_CANCELLATION_success",
  "newCaseStatus": "Case_CANCELLATION_success",
  "NewCaseNumber": "3732gy12"
         }
}

Apex Class:

public class ParsingTest
{
  public ParsingTest()
  {
      String json='{"status":"SUCCESS","errors":[],"data":{"oldCaseStatus":"Case_CANCELLATION_success","newCaseStatus":"Case_CANCELLATION_success","NewCaseNumber":"3732gy12"}}';
      ParsingWrapper apiRespone = new ParsingWrapper();
      
      apiRespone = (ParsingWrapper)System.JSON.deserialize(json,ParsingWrapper.class);
      System.debug('apiRespone..'+apiRespone);
  }

 //Wrapper Class For Parsering 

  public class ParsingWrapper
  {
   public String status{get;set;}
   public Map<String,String> data{get;set;}
   public Cls_errors[] errors;
  }

  public class Cls_errors
  {

  }
}

Hope this helps you....Enjoy!
