Typical error response

{
    "ok": false,
    "error": "invalid_auth"
}

The response contains a list of file objects, followed by paging information.

In order to gather information on tombstoned files in Free workspaces, so that you can delete or revoke them, pass the show_files_hidden_by_limit parameter. While the yielded files will still be redacted, you'll gain the id of the files so that you can delete or revoke them.

Pagination

This method uses cursor-based pagination to make it easier to incrementally collect information. To begin pagination, specify a limit value under 1000. We recommend no more than 200 results at a time.

Responses will include a top-level response_metadata attribute containing a next_cursor value. By using this value as a cursor parameter in a subsequent request, along with limit, you may navigate through the collection page by virtual page.

See pagination for more information.

Types

The file types you may encounter include (but are not limited to):

  • all - All files
  • spaces - Posts
  • snippets - Snippets
  • images - Image files
  • gdocs - Google docs
  • zips - Zip files
  • pdfs - PDF files

Errors

This table lists the expected errors that this method could return. However, other errors can be returned in the case where the service is down or other unexpected factors affect processing. Callers should always check the value of the ok params in the response.

ErrorDescription
user_not_found

Value passed for user was invalid

unknown_type

Value passed for types was invalid

not_authed

is_bot

This method cannot be called by a bot user.

invalid_arguments

The method was called with invalid arguments.

invalid_arg_name

The method was passed an argument whose name falls outside the bounds of accepted or expected values. This includes very long names and names with non-alphanumeric characters other than _. If you get this error, it is typically an indication that you have made a very malformed API call.

invalid_charset

The method was called via a POST request, but the charset specified in the Content-Type header was invalid. Valid charset names are: utf-8 iso-8859-1.

invalid_form_data

The method was called via a POST request with Content-Type application/x-www-form-urlencoded or multipart/form-data, but the form data was either missing or syntactically invalid.

invalid_post_type

The method was called via a POST request, but the specified Content-Type was invalid. Valid types are: application/json application/x-www-form-urlencoded multipart/form-data text/plain.

missing_post_type

The method was called via a POST request and included a data payload, but the request did not include a Content-Type header.

team_added_to_org

The workspace associated with your request is currently undergoing migration to an Enterprise Organization. Web API and other platform operations will be intermittently unavailable until the transition is complete.

request_timeout

The method was called via a POST request, but the POST data was either missing or truncated.

fatal_error

The server could not complete your operation(s) without encountering a catastrophic error. It's possible some aspect of the operation succeeded before the error was raised.

Warnings

This table lists the expected warnings that this method will return. However, other warnings can be returned in the case where the service is experiencing unexpected trouble.

WarningDescription
missing_charset

The method was called via a POST request, and recommended practice for the specified Content-Type is to include a charset parameter. However, no charset was present. Specifically, non-form-data content types (e.g. text/plain) are the ones for which charset is recommended.

superfluous_charset

The method was called via a POST request, and the specified Content-Type is not defined to understand the charset parameter. However, charset was in fact present. Specifically, form-data content types (e.g. multipart/form-data) are the ones for which charset is superfluous.
