Required arguments
tokenstringRequiredAuthentication token bearing required scopes. Tokens should be passed as an HTTP Authorization header or alternatively, as a POST parameter.
xxxx-xxxxxxxxx-xxxxOptional arguments
cursorstringOptionalPaginate 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.
dXNlcjpVMDYxTkZUVDI=exclude_archivedbooleanOptionalSet to true to exclude archived channels from the list
falsetruelimitnumberOptionalThe maximum number of items to return. Fewer than the requested number of items may be returned, even if the end of the list hasn't been reached. Must be an integer with a max value of 999.
10020team_idstringOptionalencoded team id to list conversations in, required if org token is used
typesstringOptionalMix and match channel types by providing a comma-separated list of any combination of public_channel, private_channel, mpim, im
public_channelim,mpimuserstringOptionalBrowse conversations by a specific user ID's membership. Non-public channels are restricted to those where the calling user shares membership.
W0B2345DUsage info
This method helps answer questions like:
- Which conversations am I a member of?
- Which public channels is my bot user in?
- Do I have any direct messages open with my friend Suzy?
- Is my bot a member of any private channels?
This method returns a list of all channel-like conversations accessible (via membership of the channel) to the user or app tied to the presented token, as part of our Conversations API.
Browse the public channel membership of other users with the user parameter. Private channel membership is only listed when the calling user, bot user, or app shares membership in a direct message, multi-person direct message, or private channel. Further filter channels by type with the types parameter.
The team_id is only relevant when using an org-level token. This field will be ignored if the API call is sent using a workspace-level token.
Response
Typical success response with only public channels. Note how num_members and is_member are not returned like typical conversations objects.

Typical error response
{
"ok": false,
"error": "invalid_auth"
}
Returns a list of limited channel-like conversation objects.
To get a full conversation object, call the conversations.info method. We omit the is_member and num_members fields in this method's response.
See conversation object for more detail on returned fields.
Pagination
This method uses cursor-based pagination to make it easier to incrementally collect information. To begin pagination, specify a limit value with a max of 999. 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.
Token support
Using a bot user token, this method returns the channels and conversations your bot is party to. Specifying a user parameter filters to conversations your bot shares with that user.
A user token armed with channels:read will similarly supply the channels the calling user is a member of. Supplying the user parameter narrows results to conversations featuring both the calling user and the identified user.
Errors
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 parameter in the response.
access_deniedAccess to a resource specified in the request is denied.
accesslimitedAccess to this method is limited on the current network
account_inactiveAuthentication token is for a deleted user or workspace when using a bot token.
deprecated_endpointThe endpoint has been deprecated.
ekm_access_deniedAdministrators have suspended the ability to post a message.
enterprise_is_restrictedThe method cannot be called from an Enterprise.
fatal_errorThe server could not complete your operation(s) without encountering a catastrophic error. It's possible some aspect of the operation succeeded before the error was raised.
internal_errorThe server could not complete your operation(s) without encountering an error, likely due to a transient issue on our end. It's possible some aspect of the operation succeeded before the error was raised.
invalid_arg_nameThe method was passed an argument whose name falls outside the bounds of accepted or expected values. This includes very long names and names with non-alphanumeric characters other than _. If you get this error, it is typically an indication that you have made a very malformed API call.
invalid_argumentsThe method was called with invalid arguments.
invalid_array_argThe method was passed an array as an argument. Please only input valid strings.
invalid_authSome aspect of authentication cannot be validated. Either the provided token is invalid or the request originates from an IP address disallowed from making the request.
invalid_charsetThe method was called via a POST request, but the charset specified in the Content-Type header was invalid. Valid charset names are: utf-8 iso-8859-1.
invalid_cursorValue passed for cursor was not valid or is no longer valid.
invalid_form_dataThe method was called via a POST request with Content-Type application/x-www-form-urlencoded or multipart/form-data, but the form data was either missing or syntactically invalid.
invalid_limitValue passed for limit is not understood.
invalid_post_typeThe method was called via a POST request, but the specified Content-Type was invalid. Valid types are: application/json application/x-www-form-urlencoded multipart/form-data text/plain.
invalid_typesValue passed for type could not be used based on the method's capabilities or the permission scopes granted to the used token.
method_deprecatedThe method has been deprecated.
method_not_supported_for_channel_typeThis type of conversation cannot be used with this method.
missing_argumentA required argument is missing.
missing_post_typeThe method was called via a POST request and included a data payload, but the request did not include a Content-Type header.
