Hi, I have used the Facebook API to get the user’s first name and gender fine, but when I try to also get their birthday. I get an error. Here is the code (It works fine for name and gender but not birthday):

    void AuthCallBack (IResult result)
    {
        if (result.Error != null)
        {
            Debug.Log(result.Error);
        }

        else
        {
            if (FB.IsLoggedIn)
            {
                //Get Username, first parametre is what you want to get, method, callback
                FB.API("/me?fields=first_name", HttpMethod.GET, DisplayUsername);
                FB.API("/me?fields=gender", HttpMethod.GET, DisplayGender);
                FB.API("/me?fields=birthday", HttpMethod.GET, DisplayBirthday);

                SceneManager.LoadScene("loggedinpage");
            }

            else
            {
                Debug.Log("not logged in");
            }
        }
    }

    void DisplayUsername (IResult result)
    {
        FacebookFirstName = result.ResultDictionary ["first_name"];
        Debug.Log(FacebookFirstName.ToString());
    }

    void DisplayGender(IResult result)
    {
        FacebookGender = result.ResultDictionary["gender"];
        Debug.Log(FacebookGender.ToString());
    }


    void DisplayBirthday(IResult result)
    {
        FacebookBirthday = result.ResultDictionary["birthday"];
        Debug.Log(FacebookBirthday.ToString());
    }

}

And here is the error:

KeyNotFoundException: The given key was not present in the dictionary.
System.Collections.Generic.Dictionary`2[System.String,System.Object].get_Item (System.String key) (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.Collections.Generic/Dictionary.cs:150)

Thanks a lot

Hello,
Did you request for the birthday permission ? because the birthday is not include in the public_profile default permission, you have to request for user_birthday :slight_smile:
