Import Faces Csv Endpoint

Import people from the CSV pasted or uploaded on the faces page.

Body: { projectId, rows: [ { name, category, position, linkedin, faceLink, email, personFields: { "Company": ["Acme"], "Movie": ["Film A"] } } ], onExisting: "skip" | "update" }

A photo URL is optional. A new person without one is created as a metadata-only person and can be made recognisable by adding a reference photo later. Unknown field names are created once before concurrent row work; a matching person's flexible-field assignments are updated even in skip mode.
