Upload file
Uploads a small file to Box. For file sizes over 50MB we recommend using the Chunk Upload APIs.
The attributes part of the body must come before the
file part. Requests that do not follow this format when
uploading the file will receive a HTTP 400 error with a
metadata_after_file_contents error code.
