I\'m using Facebook Lead Ads API. I need to retrieve all fields from a form by ID. I know I can:

• get all forms by calling //leadgen_forms

Just a warning since this answer comes first on google search.

Since Facebook API v5.0 field "qualifiers" is removed and will throw an error.

Replace it with "questions" which is similar (if not exact) syntax as qualifiers. Found out the hard way on production server...
