In my app sign up is possible from both Facebook and Google. And there is a requirement for accessing friends list/contacts to check who are all my friends that are already using the app. Now, Facebook already returns the response as a list of friends who are using the app that I integrated the FB SDK in.

I want to know is there any way to get list of contacts that are already in my app using Google APIs? Or I have to fetch emails of my contacts from Google and manually check in my DB if they exist or not and decide on my on?

Thanks in advance.

Cheers, Rahul

  • I have checked the documentation, and can retrieve list of contact from Google's people API, I just want to know if I can get the list of contacts that are already using my app which is possible in Facebook APIs. Thanks anyways. – Rahul Gupta Sep 19 '17 at 09:19

I am the product manager for Google Sign-In. This is no way to get a list of users who already using a service ... you would have to request access to and fetch a full list of a user's contacts and check for existing users in your own database.
