Tokens should be passed as an HTTP Authorization header or alternatively, as a POST parameter. Example: xxxx-xxxxxxxxx-xxxx channel_id Required The channel to convert to public. Example: C12345 Usage info ​ This Admin API method converts a private channel to a public channel. 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 ​ 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. channel_not_found The channel requested for conversion to public could not be found. channel_owner_restriction away-side SC conversion fails due to home-side being private could_not_convert_channel This channel could not be converted to public. 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. external_limited_restriction away-side SC conversion fails due to being under Limited Access (“external_limited” aka “can only post”) 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. feature_not_enabled The feature has not been enabled for this Organization 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.
