How to specify the scope of Google API to get the birthday - symfony

Question

I am trying to get the birthday from the Google API, but the retrieved data in HWIOAuthBundle do not contain it.
I am wondering if the specified scope for google plus api in config.yml is correct or not!
If not, please give a link or the corrected scope.
google:
type: google
client_id: %client_id%
client_secret: %secret_id%
scope: "https://www.googleapis.com/auth/userinfo.email https://www.googleapis.com/auth/userinfo.profile"
paths:
email: email
profilepicture: picture

Answer 1

I just used and tested it using Try It. I tested it with all of the different scopes.
https://www.googleapis.com/auth/plus.login Know your basic profile
info and list of people in your circles.
https://www.googleapis.com/auth/plus.me Know who you are on Google
https://www.googleapis.com/auth/userinfo.email View your email address
https://www.googleapis.com/auth/userinfo.profile View basic
information about your account
It doesn't appear to matter you get back the birthday in all of the scopes. But what does matter is that the Users Birthday must be set to public in the Account. If it's set to anything else, your circles, only you, it's not listed. This appears to be true even when you are trying to see your own information. (Sending Me.)
Update and the year is 2018
The People api now returns the birthday of the current user
People.get However i suspect its linked to google+ so if the user hasn't filled it out you probably wont get info.
GET https://people.googleapis.com/v1/{resourceName=people/*}
Send Resournce name of people/me and birthdays personFields
{
"resourceName": "people/117200475532672775346",
"etag": "%EgQBBzcuGgwBAgMEBQYHCAkKCwwiDDQwaGhWYzc3cXJBPQ==",
"birthdays": [
{
"metadata": {
"primary": true,
"source": {
"type": "PROFILE",
"id": "117200475532672775346"
}
},
"date": {
"month": 1,
"day": 6
}
},
{
"metadata": {
"source": {
"type": "ACCOUNT",
"id": "117200475532672775346"
}
},
"date": {
"year": 1971,
"month": 1,
"day": 6
}
}
]

Normally you will only get birthdays that have public visibility. To get private birthdays you need to use the https://www.googleapis.com/auth/user.birthday.read scope. See documentation for which scopes give you which data https://developers.google.com/people/v1/how-tos/authorizing#profile-scopes.
