File (Mini)

A mini representation of a file, used when nested under another resource.

This resource has a few variations that can be encountered when using the API.

The fields that are part of the mini variant are generally returned when the resource is nested within the response for another resource.


The unique identifier that represent 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://* the file_id is 123.



Value is always file


The HTTP etag of this file. This can be used within some API endpoints in the If-Match and If-None-Match headers to only perform changes on the file if (no) changes have happened.

The information about the current version of the file.


The name of the file


A numeric identifier that represents the most recent user event that has been applied to this item.

This can be used in combination with the GET /events-endpoint to filter out user events that would have occurred before this identifier was read.

An example would be where a Box Drive-like application would fetch an item via the API, and then listen to incoming user events for changes to the item. The application would ignore any user events where the sequence_id in the event is smaller than or equal to the sequence_id in the originally fetched resource.

string (digest)

The SHA1 hash of the file. This can be used to compare the contents of a file on Box with a local file.
