How to match and validate with the provided API in Ionic?

I could not be able to login using the test input. I have created everything accordingly but the login function is not working. Whenever I enter the sample input (phoneNumber and password) it did not directing me to the HomePage. Is there anything I am missing out. Please HELP me out. Details about API has been provided in the pictures below.

API details :



**html code:**

<ion-header>
  <ion-navbar>
    <ion-title>
      Login
    </ion-title>
  </ion-navbar>
</ion-header>

<ion-content padding>
  <ion-list>
    <form name="form"(ngSubmit)="login()" novalidate>
      <ion-item>
        <ion-label fixed>Phone Number</ion-label>
        <ion-input type="number" name="phoneNumber" value="" [(ngModel)]="model.phoneNumber" required></ion-input>
      </ion-item>

      <ion-item>
        <ion-label fixed>Password</ion-label>
        <ion-input type="password" name="password" value="" [(ngModel)]="model.password" required></ion-input>
      </ion-item>
      <ion-item>
        <button ion-button>Enter</button>
      </ion-item>
    </form>
  </ion-list>
</ion-content>

@Component({

export class LoginPage {
  model : any = {};
  response: any[] = [];
  constructor(public navCtrl: NavController, public apiService: apiService, public toastCtrl: ToastController, public alertCtrl: AlertController, public loadingCtrl: LoadingController, public AuthService: AuthService){}

  loginUser(){
    this.AuthService.login();
  }
  logoutUser(){
    this.AuthService.logout();
  }
  nextPage(data){
    this.navCtrl.push(HomePage,data).catch(err => {
      let alert = this.alertCtrl.create({
        title: 'Something',
        subTitle: 'something something',
        buttons: ['OK']
      });
      alert.present();
    });
  }
  errorToast(){
    let toast = this.toastCtrl.create({
      message: 'Cannot login',
      duration: 3000
    });
    toast.present();
  }
  logoutout(){
    let loader = this.loadingCtrl.create({
      content: "Loging out.....",
      duration: 1000
    })
    loader.present();
    this.loginUser();
  }
  login(){
    this.apiService.apiCall(this.model.phoneNumber, this.model.password)
    .then(data => {
      this.logoutout();
      this.nextPage(data);
    })
    .catch(error => {
      this.errorToast();
