Google Contacts API with Google JavaScript Client Lib

Question

I am trying to work with the Google Contacts API v3.

Because of the OAuth2 authentication and authorization I'm started with the Google APIs Client Library for JavaScript. I have no problems with that part of the API access.

But after doing the auth part I don't know what to do next. Can I use the google-api-javascript-client for the Google Contacts API v3? In the list of the supported Google APIs by the javascript-client the contacts API does not appear. But I have full access with the OAuth 2.0 Playground tool.

I am really confused which client is working best with the latest Google Contacts API. What is about the gdata-javascript-client?

Answer 1

To use the v3 contacts api with the authentication token provided by gapi (Google JS client lib) this one is helpful, using alt=&json

$.getJSON('https://www.google.com/m8/feeds/contacts/default/full/?access_token=' + 
             authResult.access_token + "&alt=json&callback=?", function(result){
      console.log(JSON.stringify(result));
});

I know it's an old question but this question shows up when looking on how to read the contacts information from a Google account.

If you only need to access the contact to import it or show the email, phone numbers, or other information and you don't need to modify it, you can use the People API (https://developers.google.com/people/). For javascript you can check the samples tab.

I created a gist, which is almost the sample from Google but adding the requestField parameters.
