Media Upload

Finish Multipart Upload

Finalizes a multipart S3 upload by submitting the part ETags returned by each chunk PUT. Only call this when [Create Signed Upload](/api-reference/media-upload/create-signed-upload) returned a multipart response (uploadId + keys[]). Single-part uploads do not need this step. Requires permission api_media_upload_signed_finish.
