This method returns a list of all channels in the team. This includes channels the caller is in, channels they are not currently in, and archived channels but does not include private channels. The number of (non-deactivated) members in each channel is also returned.
To retrieve a list of private channels, use groups.list.
Having trouble getting a HTTP 200 response from this method? Try excluding the members list from each channel object using the exclude_members parameter.
The members array found in this and other methods will begin automatically truncating at 1,500 results beginning December 1, 2017. Please Use conversations.members to manage memberships instead. Read on to learn more.
Paginate through collections of data by setting the cursor parameter to a next_cursor attribute returned by a previous request's response_metadata. Default value fetches the first "page" of the collection. See pagination for more detail.
Exclude archived channels from the list
Exclude the members collection from each channel
The maximum number of items to return. Fewer than the requested number of items may be returned, even if the end of the users list hasn't been reached.
Use the exclude_members parameter to exclude the members collection from each listed channel. This improves performance, especially with larger teams. Use channels.info to retrieve members on a channel-by-channel basis instead.
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.
Please note that the argument for the method, exclude_members may not work well with pagination at this time. Channels with very large memberships and teams with many channels may cause the method to throw a HTTP 500 error. Please exclude memberships with exclude_members and look them up atomically with channels.info instead.
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.
Value passed for cursor was not valid or is no longer valid.
No authentication token provided.
Invalid authentication token.
Authentication token is for a deleted user or workspace.
The workspace token used in this request does not have the permissions necessary to complete the request.

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.
A members array included in a channel object was truncated at 1500 results. Use conversations.members to retrieve all results.
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.
