List files (primary method)

This call returns a list of files and subdirectories in a specified project or directory within a project, with specified properties that you can access. The project or directory whose contents you want to list is specified as a query parameter in the call. Further properties to filter by can also be specified as query parameters.

Note that this call lists both files and subdirectories in the specified project or directory within a project, but not the contents of the subdirectories. To list the contents of a subdirectory, make a new call and specify the subdirectory ID as the parent parameter.

Don't forget that projects on the Platform are specified by their short names.

👍
File IDs
The file IDs returned by this call are useful for issuing further queries to get more information about a particular file.

🚧
Alias call
There is a second method for listing files in a project: GET projects/{project_owner}/{project_name}/files. The call listed here is the primary and preferred method for performing this operation.

Name	Description
`X-SBG-Auth-Token` required	Your Platform authentication token.

Query Parameters

You can use query parameters, listed in the table below, to return specific results. See the tip box below for details on OR and AND operations while filtering. Below the table, you'll see examples of API requests using various parameters.

Tips for filtering
When filtering on any resource, including the same field several times with different filtering criteria results in an implicit OR operation for that field and the different criteria.
When filtering by different specified fields, an implicit AND is performed between those criteria. Thus, the call in Example 3 above would return files matching the specified project AND sample ID AND library.

Name	Data type	Description
`project_owner` required	string	The owner of the project you are listing files from.
`project` required		The project's short name
`name`	string	List file with this name. Note that the name must be an exact complete string for the results to match. Multiple names can be separated by an `OR` operation, as shown in example 4 below. The `OR` operation is implied when the same parameter is queried multiple times in the same API request
`metadata.{field}`	string	List only files with that have the specified value in metadata field. Multiple instances of the same metadata field are implicitly separated by an `OR` operation. Conversely, different metadata fields are implicitly separated by an `AND` operation, as shown in example 3 below.
`origin.task`	string	List only files produced by task specified by ID in this field
`origin.dataset`	string	List only files which are part of the dataset specified in this field. Possible values include: `tcga`, `tcga_grch38`, `ccle`, `cptac`, and `target`.
`fields`	string	Selector specifying a subset of fields to include in the response.
`tag`	string	List files containing this tag. Note that the tag must be an exact complete string for the results to match. Multiple tags can be separated by an OR operation, as shown in example 5 below. The OR operation is implied when the same parameter is queried multiple times in the same API request. Keep in mind that tags are different from metadata. Learn more about tagging your files on the Platform.

Limit your results
Don't forget that you can use filtering with the limit parameter to restrict the number of files returned by this call.

Example requests
