Common error response

Typical error response

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

The file object contains information about the uploaded file.

Each comment object in the comments array contains details about a single comment. Comments are returned oldest first.

The paging information contains the count of comments returned, the total number of comments, the page of results returned in this response and the total number of pages available. Please note that the max count value is 1000 and the max page value is 100.

Bot user tokens may use this method to access information about files appearing in the channels they belong to.


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.


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.
