Typical error response

    "ok": false,
    "error": "invalid_auth"

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

The paging information contains the count of files returned, the total number of files matching the filter (if any was supplied), the page of results returned in this response and the total number of pages available.

If cursor paging is used, a nextCursor argument will be returned instead of the normal paging information such as count, total, page, and pages. It will be up to the client to keep track of that information, with the peace of mind that the cursor pagination will return files in a stable ordering.


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.

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.

Warning Description

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.


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.
