prepare_transfer

Stores one text file behind a temporary download link and shows a transfer card. Use only when the user wants a hosted download link. To stage a file, send file_name and content (ttl_hours is optional, 1 to 168, default 24). To check a link made earlier, send only transfer_id. Returns download_url, file_name, sha256, size_bytes, expires_at and transfer_id; ChatGPT also shows a card with the file details, time left and a download button. With no content and no transfer_id it stages nothing and returns status ready. Do not use to show a draft: draft_email, create_calendar_event and create_markdown_file already return the file text. The file is stored until the link expires.

Parameters6

file_name	string	optional	File name with its extension, such as "report.md", "invite.ics" or "draft.eml". Send it together with content to stage a file.
content	string	optional	Full text of the file to stage (at most 200,000 characters). Send it together with file_name. Without content, nothing is stored.
mime_type	string	optional	Optional MIME type, such as "text/markdown", "text/calendar" or "message/rfc822". Guessed from file_name when omitted.
ttl_hours	integer	optional	Hours until the download link expires, from 1 to 168. Default 24.
transfer_id	string	optional	ID of a transfer made earlier, from its transfer_id field (32 hex characters). Send it alone to check that link. An unknown or expired ID returns transfer_not_found.
file	object	optional	Set by ChatGPT when the user opens the card from a file. Do not fill this in yourself.
