version_onlyboolean

When true, only adds a new file version and updates the entity's s3ref to point to the new version, without overwriting the entity's existing top-level metadata. The entity's filename, type, and other fields are preserved as-is. The new version entry in the versions array will contain the file-level metadata (filename, mime_type, etc). Only applies when updating an existing entity (_id or file_entity_id is set).

Response

Created or updated File Entity

_titlestring required
_schema'file' required
_orgstring required
_tagsstring[]
_purposestring[]
_manifeststring[]

Manifest ID used to create/update the entity

filenamestring required
type'document' | 'document_template' | 'text' | 'image' | 'video' | 'audio' | 'spreadsheet' | 'presentation' | 'font' | 'archive' | 'application' | 'unknown' required
mime_typestring

MIME type of the file

size_bytesinteger

File size in bytes

readable_sizestring

Human readable file size

etagstring

Content hash (S3 ETag) of the latest file version. For single-part uploads this is the hex MD5 of the content and is stable across orgs, so identical content yields an identical etag. Used to detect real content changes without re-downloading the bytes.

access_control'private' | 'public-read' required
public_urlstring url

Direct URL for file (public only if file access control is public-read)

custom_download_urlstring uri

Custom external download url used for the file

custom_download_url_auth'presigned' | 'token'

Authorization mode for the custom_download_url. presigned (the default) uses an HMAC-signed URL; token authorizes the download via the caller's bearer token, matched against the exact stored custom_download_url. In token mode the File API returns the unsigned custom_download_url (no expires_at/signature query params) so the stored url matches exactly.

preview_summary_destring

Compact German summary for hover and list preview surfaces.

short_summary_destring

Short German paragraph summary for file preview surfaces.

preview_summary_enstring

Compact English summary for hover and list preview surfaces.

short_summary_enstring

Short English paragraph summary for file preview surfaces.

file_summary_execution_idstring uuid

AI execution that produced the current summary. Used to correlate user feedback.

source_urlstring

Source URL for the file. Included if the entity was created from source_url, or when ?source_url=true

_updated_atstring date-time
_created_atstring date-time
__additionalobject nullable

Additional fields that are not part of the schema
