Answer: 
Auth0 developer here.

Have you tried following this comprehensive tutorial? <https://auth0.com/blog/ionic-2-authentication-how-to-secure-your-mobile-app-with-jwt/>. It covers implementing Facebook and Google login for your Ionic 2 app.

You might also want to check out this <https://auth0.com/docs/quickstart/native/ionic2>.

I hope this information helps.
Finally i succeed in Facebook login API. i refer <http://ionicframework.com/docs/v2/native/facebook/> for the achiving this. 

```
onFBLoginClick()
 {
   Facebook.login(['email']).then(data=>{
     this.faceBookToken=data.authResponse.accessToken;
     this.faceBookUserId=data.authResponse.userID;

     //Call getter function
     this.onGetDetailsClick();
   });
 }

 onGetDetailsClick()
 {
   Facebook.api(this.faceBookUserId+"/?fields=name,email,birthday,gender",['public_profile']).then(data=>{
     alert(JSON.stringify(data));
   });
 }//onGetDetailsClick()

```

Thanks a lot IONIC Team...
