Invite API - how to get sender information on receiver's side about google-services HOT 3 CLOSED

get sender information (name, picture etc.) [...] on receiver's side

I don't believe that Google provides this but it is possible to use the invitation ID as a unique identifier for each invitation, store data on your site upon sending, and then retrieve the data from your site when the recipient gets the invitation. I'll forward your feature request to the app invites team. If you're using profile data, please be mindful of the developer policies for the data you're using.

know if for example sender is putting fake email in invitation?

The sender of the invitation determines the text of the final invitation that gets sent so the "invitation sender" is in effect not verified - invitations could also be sent via SMS and there's no verification of the sender because the sender has control over the message. As such, the best signal that you have to work with is data that you have verified and associated to the invitation ID: if the invitation itself is spoofed, the ID lookup would fail / the invitation would not resolve.

If you really want to get the sender information, you could just store that as part of your deep link data. Then parse it back out on the receiver's side. You can put anything you want in the deep link!
