    Upload file version

    post
    https://upload.box.com/api/2.0
    /files/:file_id/content

    This endpoint is in the version 2024.0. No changes are required to continue using it. For more details, see Box API versioning.

    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

    bearer [ACCESS_TOKEN]
    multipart/form-data

    Request Headers

    stringin headeroptional
    134b65991ed521fcfe4724b7d814ab8ded5185dc

    An optional header containing the SHA1 hash of the file to ensure that the file was not corrupted in transit.

    stringin headeroptional
    1

    Ensures 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.

    Path Parameters

    stringin pathrequired
    12345

    The 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

    string arrayin queryoptional
    id,type,name

    A 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

    objectin 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.

    string (date-time)in bodyrequired
    "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.

    stringin bodyrequired
    "Photo 2.0.png"

    An optional new name for the file. If specified, the file will be renamed when the new version is uploaded.

    string (binary)in bodyrequired

    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.

    Response

    application/jsonFiles

    Returns the new file object in a list.

    application/jsonClient error

    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.

    application/jsonClient error

    An unexpected client error.
