Register now!Upload file version
Update a file's content. 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.
Request
Path Parameters
12345The unique identifier that represents a file.
The ID for any file can be determined
by visiting a file in the web application
and copying the ID from the URL. For example,
for the URL https://*.app.box.com/files/123
the file_id is 123.
Query Parameters
id,type,nameA comma-separated list of attributes to include in the response. This can be used to request fields that are not normally returned in a standard response.
Be aware that specifying this parameter will have the effect that none of the standard fields are returned in the response unless explicitly specified, instead only fields for the mini representation are returned, additional to the fields requested.
Request Body
The additional attributes of the file being uploaded. Mainly the name and the parent folder. These attributes are part of the multi part request body and are in JSON format.
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.
"2012-12-12T10:53:43-08:00"Defines the time the file was last modified at.
If not set, the upload time will be used.
"Photo 2.0.png"An optional new name for the file. If specified, the file will be renamed when the new version is uploaded.
The content of the file to upload to Box.
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.
Request Headers
134b65991ed521fcfe4724b7d814ab8ded5185dcAn optional header containing the SHA1 hash of the file to ensure that the file was not corrupted in transit.
1Ensures this item hasn't recently changed before making changes.
Pass in the item's last observed etag value
into this header and the endpoint will fail
with a 412 Precondition Failed if it
has changed since.
Response
Returns the new file object in a list.
Returns an error when the If-Match header does not match
the current etag value of the file. This indicates that the file
has changed since it was last requested.
An unexpected client error.
