I have set up firebase authentication and am trying to send a welcome email
What I do not understand is why the authenticated user does not have an email field and only has this in the provider data. All the samples use something similar to:
exports.sendWelcomeEmail = functions.auth.user().onCreate(event => {
const user = event.data; // The Firebase user.
const email = user.email; // The email of the user.
const displayName = user.displayName; // The display name of the user.
console.log("New User created: " + JSON.stringify(user));
console.log('email:', email);
However, my authenticated user does not seem to me to have an email
My log shows
email: undefined
I am using google authentication from IOS with GIDSignInButton
My console log has the following
{
"displayName": "Ryan H",
"metadata": {
"createdAt": "2017-06-19T10:06:21.000Z",
"lastSignedInAt": "2017-06-19T10:06:21.000Z"
},
"photoURL": "https://lh6.googleusercontent.com/-MXne-lIR8e8/AAAAAAAAAAI/AAAAAAAAbeQ/Z1OvxasY/s96-c/photo.jpg",
"providerData": [
{
"displayName": "Ryan H",
"email": "ryanh#gmail.com",
"photoURL": "https://lh6.googleusercontent.com/-MXne-lIR8e8/AAAAAAAAAAI/AAAAAAAAbeQ/Z1asY/s96-c/photo.jpg",
"providerId": "google.com",
"uid": "1077081708"
}
],
"uid": "WjdlLc3QNvrmkj0yOuqo2"
}
As you can see there is no email except in the provider data.
Has there been a change in the model?
Should I always try to get my email address from the provider data?
Why are all the same code and examples I find using user.email ?
I currently have google and facebook enabled as "sign in methods".
Perhaps if I also enabled email/password I would have access.
I can confirm that in my IOS app the User after sign in does not have email either.
According to https://firebase.google.com/docs/auth/users
The first time a user signs up to your app, the user's profile data is populated using the available information:
If the user signed up with an email address and password, only the primary email address property is populated
If the user signed up with a federated identity provider, such as Google or Facebook, the account information made available by the provider is used to populate the Firebase User's profile
This is a workaround to my issue not really an answer:
I extract an email from the first provider I find, which in my case is always
Google
exports.sendWelcomeEmail = functions.auth.user().onCreate(event => {
const user = event.data; // The Firebase user.
var email = user.email; // The email of the user.
if (email == undefined) {
for (var provider of user.providerData) {
if (provider.email) {
email = provider.email;
break;
}
}
}
const displayName = user.displayName; // The display name of the user.
// [END eventAttributes]
console.log("New User created: " + JSON.stringify(user));
console.log('email:', email);
console.log('displayName:', displayName);
sendWelcomeEmail(email,displayName)
return;
});`
I have been trying to insert a Google calendar event via Google service account that was created for an app in my dev console, but I am continually getting a helpless 404 response back on the Execute method. In the overview of the dev console I can see that the app is getting requests because there are instances of errors on the calendar.events.insert method. There is no information on what is failing. I need this process to use the Service account process instead of OAuth2 so as to not require authentication each time a calendar event needs to be created.
I have set up the service account, given the app a name, have the p12 file referenced in the project. I've also, gone into a personal calendar and have shared with the service account email address. Also, beyond the scope of this ticket, I have created a secondary app, through an administration account and have granted domain wide access to the service account only to receive the same helpless 404 error that this is now giving.
Error Message: Google.Apis.Requests.RequestError
Not Found [404]

Any help identifying a disconnect or error would be greatly appreciated.

I had the same problem. The solution was to add an email client, whose calendar event you want to send.
Credential = new ServiceAccountCredential(
new ServiceAccountCredential.Initializer(serviceAccountEmail)
{
Scopes = Scopes,
User = "example_client_email#gmail.com"
}.FromCertificate(certificate));
So I found out that for this to work, You need to make sure that you access the google.Admin account for referencing the service account Client ID of the app you created.
Another thing that helps is making sure the timezone is in the following format "America/Phoenix"
I have now successfully created events through the service account WITHOUT authentication.
I am trying to get my friend name and ids with Graph API v2.0, but data returns empty:
{
"data": [
]
}
When I was using v1.0, everything was OK with the following request:
FBRequest* friendsRequest = [FBRequest requestForMyFriends];
[friendsRequest startWithCompletionHandler: ^(FBRequestConnection *connection,
NSDictionary* result,
NSError *error) {
NSArray* friends = [result objectForKey:#"data"];
NSLog(#"Found: %i friends", friends.count);
for (NSDictionary<FBGraphUser>* friend in friends) {
NSLog(#"I have a friend named %# with id %#", friend.name, friend.id);
}
}];
But now I cannot get friends!
In v2.0 of the Graph API, calling /me/friends returns the person's friends who also use the app.
In addition, in v2.0, you must request the user_friends permission from each user. user_friends is no longer included by default in every login. Each user must grant the user_friends permission in order to appear in the response to /me/friends. See the Facebook upgrade guide for more detailed information, or review the summary below.
If you want to access a list of non-app-using friends, there are two options:
If you want to let your people tag their friends in stories that they publish to Facebook using your App, you can use the /me/taggable_friends API. Use of this endpoint requires review by Facebook and should only be used for the case where you're rendering a list of friends in order to let the user tag them in a post.
If your App is a Game AND your Game supports Facebook Canvas, you can use the /me/invitable_friends endpoint in order to render a custom invite dialog, then pass the tokens returned by this API to the standard Requests Dialog.
In other cases, apps are no longer able to retrieve the full list of a user's friends (only those friends who have specifically authorized your app using the user_friends permission). This has been confirmed by Facebook as 'by design'.
For apps wanting allow people to invite friends to use an app, you can still use the Send Dialog on Web or the new Message Dialog on iOS and Android.
UPDATE: Facebook have published an FAQ on these changes here: https://developers.facebook.com/docs/apps/faq which explain all the options available to developers in order to invite friends etc.
Although Simon Cross's answer is accepted and correct, I thought I would beef it up a bit with an example (Android) of what needs to be done. I'll keep it as general as I can and focus on just the question. Personally I wound up storing things in a database so the loading was smooth, but that requires a CursorAdapter and ContentProvider which is a bit out of scope here.
I came here myself and then thought, now what?!
The Issue
Just like user3594351, I was noticing the friend data was blank. I found this out by using the FriendPickerFragment. What worked three months ago, no longer works. Even Facebook's examples broke. So my issue was 'How Do I create FriendPickerFragment by hand?
What Did Not Work
Option #1 from Simon Cross was not strong enough to invite friends to the app. Simon Cross also recommended the Requests Dialog, but that would only allow five requests at a time. The requests dialog also showed the same friends during any given Facebook logged in session. Not useful.
What Worked (Summary)
Option #2 with some hard work. You must make sure you fulfill Facebook's new rules: 1.) You're a game 2.) You have a Canvas app (Web Presence) 3.) Your app is registered with Facebook. It is all done on the Facebook developer website under Settings.
To emulate the friend picker by hand inside my app I did the following:
Create a tab activity that shows two fragments. Each fragment shows a list. One fragment for available friend (/me/friends) and another for invitable friends (/me/invitable_friends). Use the same fragment code to render both tabs.
Create an AsyncTask that will get the friend data from Facebook. Once that data is loaded, toss it to the adapter which will render the values to the screen.

Facebook has revised their policies now. You can’t get the whole friendlist anyway if your app does not have a Canvas implementation and if your app is not a game. Of course there’s also taggable_friends, but that one is for tagging only.
You will be able to pull the list of friends who have authorised the app only.
The apps that are using Graph API 1.0 will be working till April 30th, 2015 and after that it will be deprecated.
See the following to get more details on this:
User Friends
Facebook Application Development FAQ
In Swift 4.2 and Xcode 10.1:
If you want to get the friends list from Facebook, you need to submit your app for review in Facebook. See some of the Login Permissions:
Login Permissions
Here are the two steps:
1) First your app status is must be in Live
2) Get required permissions form Facebook.
1) Enable our app status live:
Go to the apps page and select your app
https://developers.facebook.com/apps/
Select status in the top right in Dashboard.
Submit privacy policy URL
Select category
Now our app is in Live status.
One step is completed.
2) Submit our app for review:
First send required requests.
Example: user_friends, user_videos, user_posts, etc.
Second, go to the Current Request page
Example: user_events
Submit all details
Like this submit for all requests (user_friends , user_events, user_videos, user_posts, etc.).
Finally submit your app for review.
If your review is accepted from Facebook's side, you are now eligible to read contacts, etc.
As Simon mentioned, this is not possible in the new Facebook API. Pure technically speaking you can do it via browser automation.
this is against Facebook policy, so depending on the country where you live, this may not be legal
you'll have to use your credentials / ask user for credentials and possibly store them (storing passwords even symmetrically encrypted is not a good idea)
when Facebook changes their API, you'll have to update the browser automation code as well (if you can't force updates of your application, you should put browser automation piece out as a webservice)
this is bypassing the OAuth concept
on the other hand, my feeling is that I'm owning my data including the list of my friends and Facebook shouldn't restrict me from accessing those via the API
Sample implementation using WatiN:
class FacebookUser
{
public string Name { get; set; }
public long Id { get; set; }
}
public IList<FacebookUser> GetFacebookFriends(string email, string password, int? maxTimeoutInMilliseconds)
{
var users = new List<FacebookUser>();
Settings.Instance.MakeNewIeInstanceVisible = false;
using (var browser = new IE("https://www.facebook.com"))
{
try
{
browser.TextField(Find.ByName("email")).Value = email;
browser.TextField(Find.ByName("pass")).Value = password;
browser.Form(Find.ById("login_form")).Submit();
browser.WaitForComplete();
}
catch (ElementNotFoundException)
{
// We're already logged in
}
browser.GoTo("https://www.facebook.com/friends");
var watch = new Stopwatch();
watch.Start();
Link previousLastLink = null;
while (maxTimeoutInMilliseconds.HasValue && watch.Elapsed.TotalMilliseconds < maxTimeoutInMilliseconds.Value)
{
var lastLink = browser.Links.Where(l => l.GetAttributeValue("data-hovercard") != null
&& l.GetAttributeValue("data-hovercard").Contains("user.php")
&& l.Text != null
).LastOrDefault();
if (lastLink == null || previousLastLink == lastLink)
{
break;
}
var ieElement = lastLink.NativeElement as IEElement;
if (ieElement != null)
{
var htmlElement = ieElement.AsHtmlElement;
htmlElement.scrollIntoView();
browser.WaitForComplete();
}
previousLastLink = lastLink;
}
var links = browser.Links.Where(l => l.GetAttributeValue("data-hovercard") != null
&& l.GetAttributeValue("data-hovercard").Contains("user.php")
&& l.Text != null
).ToList();
var idRegex = new Regex("id=(?<id>([0-9]+))");
foreach (var link in links)
{
string hovercard = link.GetAttributeValue("data-hovercard");
var match = idRegex.Match(hovercard);
long id = 0;
if (match.Success)
{
id = long.Parse(match.Groups["id"].Value);
}
users.Add(new FacebookUser
{
Name = link.Text,
Id = id
});
}
}
return users;
}
Prototype with implementation of this approach (using C#/WatiN) see https://github.com/svejdo1/ShadowApi. It is also allowing dynamic update of Facebook connector that is retrieving a list of your contacts.
Try /me/taggable_friends?limit=5000 using your JavaScript code
Or
try the Graph API:
https://graph.facebook.com/v2.3/user_id_here/taggable_friends?access_token=
If you are still struggling with this issue on a development mode.
Follow the same process as mentioned below:
create a test app of your main app,
create test users, automatically install app for test users and assign them 'user_friend' permission.
Add your test users as a friend with each other.
I followed the same process after going through alot of research and finally it worked.
In the Facebook SDK Graph API v2.0 or above, you must request the user_friends permission from each user in the time of Facebook login since user_friends is no longer included by default in every login; we have to add that.
Each user must grant the user_friends permission in order to appear in the response to /me/friends.
let fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()
fbLoginManager.loginBehavior = FBSDKLoginBehavior.web
fbLoginManager.logIn(withReadPermissions: ["email","user_friends","public_profile"], from: self) { (result, error) in
if (error == nil) {
let fbloginresult : FBSDKLoginManagerLoginResult = result!
if fbloginresult.grantedPermissions != nil {
if (fbloginresult.grantedPermissions.contains("email")) {
// Do the stuff
}
else {
}
}
else {
}
}
}
So at the time of Facebook login, it prompts with a screen which contain all the permissions:
If the user presses the Continue button, the permissions will be set. When you access the friends list using Graph API, your friends who logged into the application as above will be listed
if ((FBSDKAccessToken.current()) != nil) {
FBSDKGraphRequest(graphPath: "/me/friends", parameters: ["fields" : "id,name"]).start(completionHandler: { (connection, result, error) -> Void in
if (error == nil) {
print(result!)
}
})
}
The output will contain the users who granted the user_friends permission at the time of login to your application through Facebook.
{
data = (
{
id = xxxxxxxxxx;
name = "xxxxxxxx";
}
);
paging = {
cursors = {
after = xxxxxx;
before = xxxxxxx;
};
};
summary = {
"total_count" = 8;
};
}
I am using FBLoginView to login authentication and get user info in my iOS Application.
I got all the information of FB user using FBLoginView and its below delegate method
-(void)loginViewFetchedUserInfo:(FBLoginView *)loginView user:(id<FBGraphUser>)user{
}
Response is :-
bio = "some bio";
email = "email address";
"first_name" = My first name;
gender = male;
id = my id;
"last_name" = my last name;
link = "face book url link";
locale = "en_US";
name = "my full name";
timezone = "5.5";
"updated_time" = "2014-05-29T12:59:48+0000";
verified = 1;
now problem is that I am not getting the user's phone number only.
any help ?
thanks in advance.
No its not possible to get phone number because below link says that there is no phone number permission.
Click here.
I think because of FBLoginView, and new Facebook SDK of iOS you're facing this problem.

I'm using code from this tutorial (of course, not all). Everything works perfectly, but when I tried to pass email, I have System.Collections.Generic.KeyNotFoundException. Why? How can I pass e-mail value from Facebook?
return View("ExternalLoginConfirmation", new RegisterExternalLoginModel {
UserName = result.UserName,
ExternalLoginData = loginData,
FullName = result.ExtraData["name"],
Email = result.ExtraData["email"],
ProfileLink = result.ExtraData["link"],
});
This works:
return View("ExternalLoginConfirmation", new RegisterExternalLoginModel {
UserName = result.UserName,
ExternalLoginData = loginData,
FullName = result.ExtraData["name"],
//Email = result.ExtraData["email"],
ProfileLink = result.ExtraData["link"],
});
Regards
Facebook doesn't share Email addresses by default. See this post for more information, but you can change your registration model to require email when making a user registration for your site. Also, you can check that the collection has the key first, before trying to access it
AuthenticationResult result =
OAuthWebSecurity
.VerifyAuthentication(
Url.Action("ExternalLoginCallback", new { ReturnUrl = returnUrl }));
// Log in code
if (result.ExtraData.ContainsKey("email"))
// Use email
