application/x-www-form-urlencoded application/json Arguments
Required arguments
tokenstringRequiredAuthentication token bearing required scopes. Tokens should be passed as an HTTP Authorization header or alternatively, as a POST parameter.
xxxx-xxxxxxxxx-xxxxchannel_idstringRequiredThe encoded channel_id to add or remove to workspaces.
Optional arguments
team_idOptionalThe workspace to which the channel belongs if the channel is a local workspace channel. Omit this argument if the channel is a cross-workspace or org-wide shared channel.
target_team_idsarrayOptionalA comma-separated list of workspaces to which the channel should be shared. Not required if the channel is being shared org-wide.
T1234,T5678,T9012,T3456org_channelbooleanOptionalTrue if channel has to be converted to an org channel
falsetrueUsage info
This Admin API method sets the workspaces connected to a channel.
When used with the team_id parameter, this method sets the requested channel_id as a regular channel on the team_id workspace.
When used with the target_team_ids parameter, this method sets the requested channel_id as a cross-workspace shared channel. The channel is shared to all the workspaces in target_team_ids.
Either way, this method can be used both to add and to remove workspaces from a channel, including the workspace that originated the channel.
To access a channel's message history before the process is complete, a hard refresh is required. Additionally, for particularly larger requests, the process may take some time.
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.

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.
cannot_add_legacy_disconnected_channel_to_workspacesCannot add legacy disconnected channel to workspaces
cannot_move_local_channelThis API cannot be used to move a local channel from one workspace to another.
channel_cannot_be_unsharedChannel cannot be unshared from this workspace.
channel_not_foundThe channel wasn't found or isn't shared to this workspace.
channel_type_not_supportedThe requested channel_id is not a supported type of channel.
could_not_set_teams_for_channelThe requested channel_id has not been shared with the target workspace.
default_org_wide_channelDefault org wide channel cannot be unshared from a workspace.
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.
externally_shared_or_disconnected_channelThe channel is or was externally shared.
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.
