facebook api not returning email - facebook

Question

I am trying to return user email address using facebook api. Few days ago it was working fine, but today stopped working, and don't know why.
So first I get access token:
FB.login(response => {
if (response.authResponse) {
resolve(response.authResponse.accessToken);
} else {
reject({
error: 'User cancelled login or did not fully authorize.'
});
}
}, {
scope: 'public_profile,email'
});
then I try to get user data
FB.api('/me', {fields: 'first_name,last_name,email'}, function(response) {
console.log(response);
});
but I only get data for first_name and last_name. There is no email.
Also when I ask for permissions, it gives me email as granted, but as I said, email is not returned.
FB.api('/me/permissions', function(response) {
console.log(response);
});
Does anyone knows what can be the problem?
BTW: I am using API v2.4.

Answer 1

FB.api('/me?fields=email,name', function(response) { /* stuff here */ });
Try adding your return fields to your request.

Answer 2

I know this is old question however if someone still seraching for answers then following workaround worked for me.
You need to add email in scope scope="public_profile,email".
<fb:login-button scope="public_profile,email" autologoutlink="false" onlogin="OnRequestPermission();"></fb:login-button>

Answer 3

A possible cause is that the user did not validate the email. Try with another user with validated email to make sure this is not the problem.

Answer 4

If you set all code correctly and still don't get an email from API. The user probably doesn't have an email bound to the account or the email not confirmed by the user.

Answer 5

I made it work using a promise and adding {scope:'email'} to the initial request then including 'email' in the fb.api fields.
fb.login({scope:'email'}).then(function (resp) {
if (resp.status === 'connected') {
fb.api('/me', 'get', {fields:'id,email,first_name,gender,...'}).then(function (FbUserData) {
console.log(FbUserData);
});
}
});

I spent a lot of time trying to figure out why the email is not returned on the FacebookLoginASPnetWebForms Asp.Net application (https://github.com/nickpinheiro/FacebookLoginASPnetWebForms).
I got it working, thanks to N Nem's post above (thanks!).
Open Default.aspx.cs
In HyperLink1.NaviagteUrl, add the query string parameter: &scope=public_profile,email
HyperLink1.NavigateUrl = "https://www.facebook.com/v2.4/dialog/oauth/?client_id=" + ConfigurationManager.AppSettings["FacebookAppId"] + "&redirect_uri=http://" + Request.ServerVariables["SERVER_NAME"] + ":" + Request.ServerVariables["SERVER_PORT"] + "/account/user.aspx&response_type=code&state=1&scope=public_profile,email";
I also had to fix some bugs to parse the access token correctly.
This time, the email address is available! I hope this helps?

Answer 7

N Nem above fixed for me. Had the code correct, but missing the scope on the login button. Code I use is below.
function statusChangeCallback(response){
if(response.status === 'connected'){
registerUser(response);
}
}
function checkLoginState() {
FB.getLoginStatus(function(response) {
statusChangeCallback(response);
});
}
function registerUser(statusResponse){
let userId = statusResponse.authResponse.userID;
FB.api('/'+userId+'/?fields=id,email,first_name,last_name',function(response){
if(response && !response.error){
console.log(response);
}
});
}

This is kinda old post but I am sharing the solution that worked for me.
FB Login SDK version: v6.0
First, make sure that the user (which is you for testing purposes) has a valid/verified email. Refer to the code below.
FB.login(response => {
// your code
}, {
scope: 'public_profile,email',
return_scopes: true,
auth_type: 'rerequest'
});
And in getting the user details
const response = await axios({
method: 'get',
url: 'https://graph.facebook.com/v6.0/me?fields=id,name,email&access_token=ACCESS_TOKEN&pretty=0&sdk=joey&suppress_http_code=1'
});
I've added the parameter fields=id,name,email
