Kindly lets know if you were assisted
With due respect to Mathew, that guide is already deprecated so it's not useful anymore. Please use this instead:
Facebook Integration is used only to collect data from the form user's facebook page. Example, instead of creating a name, email, and address fields in your form, you can have the form user login to his facebook account instead and then as soon as the form gets submitted, the name and address details from the user's Facebook account will be included in the form submission. You will also have options on what data to collect from the user's Facebook account when you integrate your form.
