google plus circle in appengine

[kcc pac]

hi all,

how can I email to members in google plus circle using the member google+ Id? or other ways to info the members.. Apparently, the email can not be retrieved by using google plus people API.

Thanks.

Hi,

I'm pretty sure you can actually get the email from an ID. As explained here, a "people:get" gives you all the info shown here, which does contain emails. Maybe if the user didn't give permission for the email scope that won't work?

Cheers

Patrice,

Thank you for your reply. 

Yes, the people:get call is able to retrieve email information for the user (after google login) but not his google circle members. From my googling, it says that the email address is not disclosed across his google plus circle members. Just wonder how gmail can retrieve the email address after login through Google plus.

Hi again,

I did misunderstand your request, apologies for that.

In a single call, it will not be possible, but I believe that you can do a "people:list" with the "collection" set to visible. That will give you all users in someone's circle. From there, you can do single calls to "people:get" to get their email.

Cheers

I use exactly the calls you suggested. But, the email field is null.

Hi Colin,

Hmm, I see. I am starting to think this is expected behavior then (not extremely familiar with the Google+ API). The way I understand it from the docs explaining what you get in "emails[]" from a person resource, you need to have THAT person grant the email scope to your application as well. When you think about it, it makes sense.

If user A granted your application the scope to get their email, why should you get access to the email of user B, that's in his circle, if user B didn't explicitly grant you access to HIS email.

The documents could be clearer about this, but I do believe it makes sense. Don't you?

Cheers!

Patrice,

This is a design issue to me. From my investigation in the issue, it is deliberately not to expose email address among google plus circle members (due to the potential spam issues). The aim is to force to use other means (activities and post in Google Plus platform) for communication purpose. But, shouldn't the user give his consent when joining the circle? And again, that is the reason why I ask if there are other means to communicate privately between circle owner and its members..

Hi Colin,

So, I think you have it right here. Indeed, this is to obscure the email of the user.

In any case, if User B gives access to his email to User A, it makes sense that an application requesting the email of User B (even if on behalf of User A), doesn't get that field.

I do believe that activities and posts will be your only way to communicate. Maybe someone else who is active on the group might have suggestions though.

Cheers

That's just not how Google+ works -- you can put any other G+ member in one or more of your circles: he or she gets *informed* of the fact (and offered a chance to do the same, with a reminder that's totally optional), but, not asked for permission.
