Direct Uploads

Direct Uploads

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. For more details, please refer to our pricing comparison page.

To confirm the file size limit for your account, log into Box. Click on the circle in the top right corner and select Account Settings from the dropdown menu. On the page that displays, scroll down to the Account Details section. Your Max File Size is listed here.

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.
