I want get one specific entry from JSON data and console .log it + my params don't work

Hello i am getting a JSON data from a webservice and i push parameter Code which should console.log only the specific Code data from the JSON but in result i get all the JSON data with all the codes listed.
Is there any way that i can console log only the specific Code that i want?or to set the params in a better way in order for the webservice to read them?
Thanks in advance

 getScrid(url, paramsScrid ){
    return this.http.get
    (this.url3, paramsScrid);
  }

  scrid() {
    console.log("Entered into Scrid");
    this.url = webApihost + "api/rpc/SimpleScrollerRootTable/" + scrid;
    //this.paramsScrid.data.Code="0013168";
    this.paramsScrid = {
      type: "GET",
      headers: {
        Authorization: 'Bearer ' + this.token
      },
      data: {
        Code: "0013168"
      }
    };
    return this.getScrid(this.url, this.paramsScrid)
      .subscribe((Scrid:any) => {
        console.log(JSON.stringify(Scrid));
     });
  }

Your text and code is a bit confusing. What exactly is your problem? What is blocking you?

instead of gettting this ->

[{"Mobile1":"6946504924","Code":"0007130","Name":"ΚΡΕΜΥΔΑΣ ΤΑΣΣΟΣ"},{"Mobile1":"6977263273","Code":"0007134","Name":"ΚΥΡΙΑΚΟΠΟΥΛΟΣ ΧΑΡΗΣ"},{"Mobile1":"6982773110","Code":"0007145","Name":"Καγιαμπάκη }]

To get this only in console.log–>

[{"Mobile1":"6977263273","Code":"0007134","Name":"ΚΥΡΙΑΚΟΠΟΥΛΟΣ ΧΑΡΗΣ"}]

That looks like the second entry of your list.
Do you want to extract that from the list?
Or do you want the server only to return this?

only the server to return this.

Then you have to talk to the server developer how you can achieve this.

But i have a similar file with code which takes the parameters and runs smoothly.

In your scrid() method your local variable scrid is not defined anywhere, so your this.url is incomplete and your REST api endpoint returns all items.

scrid is defined on the top of my file ,out of the class , just before @Injectable()
