Upload File Version
Upload File Version
To upload a new version of a file to Box via direct upload, make an API call to
the POST /files/:id/content API with the content of the file, the
desired file name, and the folder ID.
curl -i -X POST "https://upload.box.com/api/2.0/files/12345/content" \
-H "authorization: Bearer <ACCESS_TOKEN>" \
-H "content-type: multipart/form-data" \
-F attributes='{"name":"Contract.pdf", "parent":{"id":"11446498"}}' \
-F file=@<FILE_NAME>await client.uploads.uploadFileVersion(file.id, {
attributes: {
name: file.name!,
} satisfies UploadFileVersionRequestBodyAttributesField,
file: generateByteStream(20),
} satisfies UploadFileVersionRequestBody);client.uploads.upload_file_version(
file.id, UploadFileVersionAttributes(name=file.name), generate_byte_stream(20)
)await client.Uploads.UploadFileVersionAsync(fileId: file.Id, requestBody: new UploadFileVersionRequestBody(attributes: new UploadFileVersionRequestBodyAttributesField(name: NullableUtils.Unwrap(file.Name)), file: Utils.GenerateByteStream(size: 20)));BoxFile file = new BoxFile(api, "id");
FileInputStream stream = new FileInputStream("My File.txt");
file.uploadNewVersion(stream);file_id = '11111'
file_path = '/path/to/file.pdf'

print(f'File "{updated_file.name}" has been updated')using (FileStream fileStream = new FileStream(filePath, FileMode.Open))
{
BoxFile file = await client.FilesManager
.UploadNewVersionAsync("File v2.pdf", "11111", fileStream);
}var fs = require('fs');
var stream = fs.createReadStream('/path/to/file.pdf');

}Request Format
The request body of this API uses a content type of multipart/form-data. This
is used to transmit two parts, namely the file attributes and the file's actual
content.
The first part is called attributes and contains a JSON object with
information about the file, including the name of the file and the id of the
parent folder.
The following is an example a test.txt being uploaded to the root folder of
the user.
POST /api/2.0/files/123/content HTTP/1.1
Host: upload.box.com
Authorization: Bearer [ACCESS_TOKEN]

Options
To learn more about all the parameters available when uploading files, head over
to the reference documentation for this API call. These parameters
include a content-md5 that can be set to ensure a file is not corrupted in
transit, and the ability to explicitly specify the file creation time at a
different time than the upload time.
For file versions an additional if-match header can be passed
along to prevent overwriting a file that has already been updated since the
application last inspected the content.
Restrictions
Direct uploads are limited to a maximum file size of 50MB. For larger files, please use the chunked upload APIs.
Upload limits are dictated by the type of account of the authenticated user. More information can be found in our community article on this topic.
