Offers an existing upload session to a signed-in person with asset write access in its workspace. Only the same OAuth connection or API key that created the session can request this fallback. The file, metadata, capacity reservation and one-hour deadline stay unchanged. Repeating the request returns the same page for a pending session. A non-pending session returns its current state without a browser URL. Enabling the handoff allows any currently authorized person in that workspace to complete or cancel it, independently of the original connection's continued access. The person must select matching file bytes; opening the page never publishes them.
参数
upload_idstringID of the media-library upload session.
响应载荷
sessionThe original upload session and any saved publication receipt. In this response, session.next is empty; follow the top-level next steps.
显示子属性
session.idsession.stateUpload progress. Pending accepts a transfer; finalizing is checking and publishing it. Completed has a saved result. Rejected, cancelled and expired allow no new upload instruction or publication. An already issued upload URL can remain usable until its expiry.
Possible values: pending, finalizing, completed, rejected, cancelled, expired
session.expires_atAbsolute session expiry. Completion must finish before this deadline; starting it or refreshing an upload instruction does not extend it.
session.nameFrozen display name for a newly published asset.
session.alt_textFrozen alternative text, or null when omitted.
session.folder_idFrozen destination folder, or null for the library root.
session.fileExact properties of the original file. Calculate size and SHA-256 from its bytes before creating a session. Images allow up to 5,242,880 bytes; other supported media allow up to 25,000,000 bytes.
session.resultSaved publication receipt, or null until completed.
显示子属性
session.result.asset_idsession.result.reused_existingWhether the upload reused an existing active asset with identical source bytes. Reused assets keep their original metadata and folder.
session.result.completed_atWhen publication completed.
session.assetCanonical asset when available, or null before completion or when unavailable.
browser_urlBird page for a pending session, or null when it no longer accepts an upload. The link grants no access; the person must sign in and have asset write permission in the workspace.
