update_payload | object or string | Yes | - | Raw LinkedIn leadForms partial-update body, forwarded unchanged. Accepts a JSON object or JSON string. Archive example: {“patch”:{“$set”:{“state”:“ARCHIVED”}}}. Use the form’s locale for localized text. Draft/unattached forms, or forms linked only to draft campaigns, allow edits to all editable fields. Published forms allow limited edits to headline, description, legal disclaimer, privacy/landing URLs, thank-you message/CTA and status; published forms linked to Sponsored InMail or Conversation Ads cannot be edited. LinkedIn documents PUBLISHED to ARCHIVED; do not assume other state transitions are supported. Archiving stops associated ads from serving. Changing questions may require remapping fields in a connected CRM. LinkedIn validates the payload. |
