The most straightforward way to upload a file to Box is using a direct upload. Direct uploads allow an application to upload a file in one request. For file sizes over 50MB we recommend using the chunked upload endpoint. The maximum file size limit for uploads to Box varies depending on your account type.

Upload domain

Uploads to Box happen via a different domain (upload.box.com) than regular API calls. This is something to keep in mind when writing your own upload code. All official Box SDKs will take care of choosing the right domain for each API call.
