create_upload

Start an upload

Reserve an upload and get a presigned URL to PUT the bytes to. Send the returned upload_headers on that PUT exactly as given — they are signed into the URL, and a missing one is a 403, not a network failure. Follow with complete_upload once the PUT succeeds.

Limits: images and audio up to 50 MB, video up to 250 MB.

If this client cannot make an HTTP request of its own, or the PUT is refused, use request_upload_link (or import_media for a file at a URL).

Scope

generation.write — Makes, edits, imports, shares and deletes media in the account.

Behaviour

Writes: Creates or changes items in the caller's own account.
Adds or updates: Adds or updates; nothing the caller already has is deleted or overwritten.
Stays in the account: Stays inside the caller's private Kuro account: any media provider it calls acts on Kuro's account, and the result is visible to no one else.
