How to get form fields in Facebook Lead Ads API?

Question

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

Answer 1

You can get these by adding non-default field qualifiers, so the url becomes /?fields=id,name,qualifiers.

I haven't found it anywhere in the official docs though. But it is quite common for new FB features to be poorly documented.

Example output

{
  "id": "1234567890000",
  "name": "test form",
  "qualifiers": [
    {
      "field_key": "first_name",
      "label": "First Name",
      "question": "First name",
      "id": "777888999000111"
    },
    {
      "field_key": "last_name",
      "label": "Last Name",
      "question": "Last name",
      "id": "111222333444555"
    }
  ]
}
