Issues a presigned S3 PUT for a CSV/XLS/XLSX import file larger than the 10MB multipart line (up to 50MB). PUT the raw file bytes to uploadUrl with the same Content-Type you declared, within expiresIn seconds (600), then pass the returned importId to POST /business/imports for the preview, or straight to POST /business/imports/{importId}/commit. Nothing is parsed or billed at this step.
Errors:
422IMPORT_FILE_UNSUPPORTED — The presign service refused the content type (reachable only if its allow-list and the documented enum drift apart).
422VALIDATION_FAILED — filename missing/blank or contentType outside the three supported MIME types.
429RATE_LIMITED — The lists rate bucket (120 requests/minute, 10,000/day per token owner) is exhausted.
Requires one of the following token scopes: lists.
Original file name, e.g. leads.csv (1-500 characters). Free text kept for your own reference: it does not name the stored object, and the file's format is read from contentType alone, so an extension that disagrees with contentType changes nothing.
MIME type of the file to upload: text/csv, application/vnd.ms-excel (XLS) or application/vnd.openxmlformats-officedocument.spreadsheetml.sheet (XLSX); the PUT to uploadUrl must send the same Content-Type.
