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.
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.
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.
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.
