How to retrieve `custom_disclaimer_responses` in Facebook lead gen webhook data - facebook

Question

I have set up a webhook that gets data submitted from a lead gen ad on Facebook.
In my response I have access to field_data and can see names and email address coming through but can't seem to find where the custom_disclaimer_responses is.
I am using the graph API explorer to send test submissions and getting a successful response
My webhook code is as follows:
exports.webhook = function (req, res, next) {
var lead = req.body.entry[0].changes[0].value;
var leadID = lead.leadgen_id;
var formID = lead.form_id;
var customDisclaimerResponses = lead.custom_disclaimer_responses
fs.readFile(config.token, 'utf8', function(err, data) {
if (err) {
console.log('err', err)
throw err;
}
var content = JSON.parse(data);
if(!content.access_token) {
console.log('Facebook Access Token is invalid.');
res.sendStatus(400);
} else {
FB.options({accessToken: content.access_token});
FB.api('/' + leadID, function (response) {
if(response && response.error) {
console.log('error', response.error);
res.sendStatus(400);
} else {
var fields = response.field_data;
// do stuff here with fields
// Response moved to outside of above function block since Facebook will
// stop sending updates if the webhook starts giving errors repeatedly.
res.sendStatus(200);
}
});
}
});
}
Example of response:
{ created_time: '2016-11-17T09:52:44+0000',
id: '<id>',
field_data:
[ { name: 'email', values: [Object] },
{ name: 'first_name', values: [Object] },
{ name: 'last_name', values: [Object] },
{ name: 'city', values: [Object] },
{ name: 'date_of_birth', values: [Object] }
]
}

I don't use webhooks, but I think this can help you:
You can add the parameter fields=custom_disclaimer_responses to get the data you need.
I re-join collected data (the ones in field_data got without parameter) by user id
This is my PHP code, for example:
$url = "https://graph.facebook.com/v2.9/$leadForm/leads?access_token=".$appToken;
$urlCustom = "https://graph.facebook.com/v2.9/$leadForm/leads?fields=custom_disclaimer_responses&access_token=".$appToken;
