      PUThttps://s3. .backblazeb2.com/<your-bucket-name>/<your-key>?partNumber=&uploadId=

      This operation uploads a part in a multipart upload.

      You must initiate a multipart upload (see S3 Create Multipart Upload) before you can upload any part. In response to your initiate request, Backblaze B2 Cloud Storage returns an UploadId, a unique identifier that you must include in your upload part request.

      AUTHORIZATION AWS Signature

      This request is using AWS Signature from collection Backblaze B2 Cloud Storage S3 Compatible API.

      Note
      If Live Read is enabled, the same part size must be used in an Upload Part request unless the part number in the request is larger than or equal to the highest part number previously uploaded.

      An invalidArgument error is returned when a part is uploaded that is not the last part but has a part size that is different than the Live Read part size.
