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:

  1. Create a new Slack app. Your app will need to be able to handle a standard OAuth 2 flow.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
