Hello there!

Could you please share more information about your code?

this.leaddetails is array of json. so, you’ll have to use for loop to get senderNewCall value for all entries.

ionViewDidLoad()  {
 
     this.http.get(this.URL+this.userID)
     
      .subscribe(data => {
       this.leaddetails = data.viewleaddetails;
       for(var i = 0; i < this.leaddetails.length; i++){
             console.log(this.leaddetails[i].senderNewCall); //here you'll get sendernewcall value for all entry
       }
      }, error => {
        //console.log(error);// Error getting the data
        alert("No Internet connection!")
      });

  }
