Facts ​ Description List all disconnected channels—i.e., channels that were once connected to other workspaces and then disconnected—and the corresponding original channel IDs for key revocation with EKM.

Tokens should be passed as an HTTP Authorization header or alternatively, as a POST parameter. Example: xxxx-xxxxxxxxx-xxxx Optional arguments channel_ids string Optional A comma-separated list of channels to filter to. team_ids string Optional A comma-separated list of the workspaces to which the channels you would like returned belong. limit integer Optional The maximum number of items to return. Must be between 1 - 1000 both inclusive. Default: 100 Example: 100 cursor string Optional Set cursor to next_cursor returned by the previous call to list items in the next page. Example: 5c3e53d5 Usage info ​ This method only applies to Enterprise organizations using Enterprise Key Management with Slack Connect channels. This Admin API method returns the original connected channel IDs used for EKM encryption keys. Use this method if you wish to revoke keys on read-only ( frozen ) channels. Frozen channels can be created when a channel shared with another organization is subsequently disconnected. When used with the team_ids parameter, this method will return all read-only (frozen) channels and their corresponding original channel_ids on the provided workspaces. When used with the channel_ids parameter, this method will filter its response, returning the specific original channel IDs requested for the given frozen channels. This admin scope is obtained through version two of the OAuth V2 flow, but there are a few additional requirements. The app requesting this scope must be installed by an admin or Owner of an Enterprise organization. Also, the app must be installed on the entire org, not on an individual workspace. See below for more details. If the app is installed by an Org Admin or Owner, ensure the Channel Management settings provide the appropriate permissions. The Org Admin or Owner installing the app must have the Channel Management role, and must also be granted access to Public channels and Private channels within this role. If these criteria aren't met, the Org Admin or Owner will receive a not_allowed error when attempting to install an app. Admin API endpoints reach across an entire Enterprise organization , not individual workspaces. For a token to be imbued with Admin scopes, it must be obtained from installing an app on the entire Enterprise org , not just a workspace within the organization. To configure and install an app supporting Admin API endpoints on your Enterprise organization: * Create a new Slack app . Your app will need to be able to handle a standard OAuth 2 flow . * In the app's settings, select OAuth & Permissions from the left navigation. Scroll down to the section titled Scopes and add the admin.* scope you want. Click the Save Changes button. * In the app's settings, select Manage Distribution from the left navigation. Under the section titled Share Your App with Other Workspaces , make sure all four sections have the green check. Then click the green Activate Public Distribution button. * Under the Share Your App with Your Workspace section, copy the Sharable URL and paste it into a browser to initiate the OAuth handshake that will install the app on your organization. You must be logged in as an admin or Owner of your Enterprise organization to install the app. * Check the dropdown in the upper right of the installation screen to make sure you are installing the app on the organization, not an individual workspace within the organization. See the image below for a visual. * Once your app completes the OAuth flow, you will be granted an OAuth token that can be used for calling Admin API methods for your organization. When installing an app to use an Admin API endpoint, be sure to install it on your Enterprise organization, not a workspace within the organization. Response ​ Typical success response { "ok" : true , "channels" : [ { "id" : "string" , "internal_team_ids" : "array" , "original_connected_host_id" : "string" , "original_connected_channel_id" : "string" } ] } 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. Error Description access_denied Access to a resource specified in the request is denied. accesslimited Access to this method is limited on the current network account_inactive Authentication token is for a deleted user or workspace when using a bot token. deprecated_endpoint The endpoint has been deprecated. ekm_access_denied Administrators have suspended the ability to post a message. enterprise_is_restricted The method cannot be called from an Enterprise. fatal_error The 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_error The 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_name The 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_arguments The method was called with invalid arguments. invalid_array_arg The method was passed an array as an argument. Please only input valid strings. invalid_auth Some 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_charset The 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_cursor Invalid cursor. invalid_form_data The 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_limit The value passed for limit was not valid. invalid_post_type The 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 . method_deprecated The method has been deprecated. missing_post_type The method was called via a POST request and included a data payload, but the request did not include a Content-Type header. missing_scope The token used is not granted the specific scope permissions required to complete this request. no_permission The workspace token used in this request does not have the permissions necessary to complete the request. Make sure your app is a member of the conversation it's attempting to post a message to. not_allowed_token_type The token type used in this request is not allowed. not_an_admin This method is only accessible by Org owners and Admins. not_authed No authentication token provided. not_enabled The API endpoint is not enabled for your team. org_login_required The workspace is undergoing an enterprise migration and will not be available until migration is complete. ratelimited The request has been ratelimited. Refer to the Retry-After header for when to retry the request. request_timeout The method was called via a POST request, but the POST data was either missing or truncated. restricted_action The caller of this API is not allowed to perform this operation. service_unavailable The service is temporarily unavailable team_access_not_granted The token used is not granted the specific workspace access required to complete this request. team_added_to_org The workspace associated with your request is currently undergoing migration to an Enterprise Organization. Web API and other platform operations will be intermittently unavailable until the transition is complete. token_expired Authentication token has expired token_revoked Authentication token is for a deleted user or workspace or the app has been removed when using a user token. two_factor_setup_required Two factor setup is required. unsupported_arguments The provided method arguments are not supported.
