[Ids in: none. Ids out: experience[].id: profile entry id; education[].id: profile entry id.]
Read or edit the connected LinkedIn account owner's OWN profile on LinkedIn: headline, about, location, a website link, ONE experience or education entry per call (add or edit), skills (add), the profile picture and cover picture (from an image link), and the "open to work" preferences. A picture goes in a call of its own, never with an experience or education entry. Call it with no fields to read the profile as it is now (headline, about, location, pictures, skills, and every experience / education entry with its id) — the starting point for proposing an edit. An edit changes the real, public profile and has no undo, so it is preview-first: call with confirm:false (the default) to see each field's current value next to the new one — nothing changes — show that to the user, and call again with the same fields and confirm:true only after their explicit yes. Only the fields you pass are sent; everything else on the profile is left as it is. To EDIT an existing experience or education pass its id; without an id a NEW entry is added. For location pass a place name (the preview shows which LinkedIn place it matched, plus alternatives to pick with locationId). Not possible here: changing the name, removing a skill or a picture, turning "open to work" off, picture filters or cropping — those are done on LinkedIn itself. Works on live senders only. After a change LinkedIn can take a minute to show it.
