}This endpoint requires authentication. Include your Bearer token in the Authorization header.
Description
PATCH /source-creator/sessions//header-rows Description: Re-downloads the session’s original file bytes (from the linkedFileDetectionSession’s GCS path) and re-parses using a new
headerRows value — useful for prelude-shaped files (e.g.
merlin_pandora, merlin_spotify) where the real data header sits
below a metadata banner. Re-runs source matching and period
detection against the new headers and clears any prior AI-suggested
/ user-confirmed mappings (column identity changed). Only supported
for sessions created via the file-detection flow
(FileDetectionSessionId set) and only for CSV/TSV — not Excel, and
not sessions uploaded directly via /analyze without a linked
detection session.
Authorization:
- Requires
