Why Are My Facebook Graph API v2.4 `/me` Requests Missing Expected Fields?

FB.api('/me') Response Discrepancies in Graph API v2.4

When attempting to retrieve basic user information using Facebook's JavaScript SDK, users may encounter discrepancies between the fields expected and those returned. In Graph API v2.4 and later, certain fields are no longer included by default.

Expected Fields

In previous versions of the API, a simple request to /me would return basic information such as the user's name (name) and ID (id). However, in v2.4 , additional fields must be explicitly requested.

Solution

To resolve this issue, specify the fields you need using the fields parameter in the FB.api call. For example, to retrieve email, first name, last name, and birthday, use the following code:

FB.api('/me', 'get', { access_token: token, fields: 'id,name,email,first_name,last_name,birthday' }, function(response) {
    console.log(response);
});

Additional Information

This change was introduced in Graph API v2.4 to improve performance, especially on mobile networks. By requiring explicit field requests, the API can optimize data retrieval and reduce unnecessary traffic.
