To get a full conversation object, call the conversations.info
method.
Use conversations.members
to retrieve and traverse membership.
See conversation object for more detail on returned fields.
Some fields in the response, like unread_count
and unread_count_display
, are included for DM conversations only.
Pagination
This method uses cursor-based pagination to make it easier to incrementally collect information. To begin pagination, specify alimit
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
