You can delete an existing integration in the DRS portion of the Spok Server.
In order to delete an integration after it has been initialized and devices have been registered, you must remove the registered devices from the Spok Mobile System.
Access the Spok Enterprise Administration interface.
Navigate to Administration > System Configuration > Integration to view the Manage Integration Settings screen, as shown below.
From the list of available integrations, click the Delete link next to the integration you would like to delete. A warning dialog will appear.
Click Yes in the warning dialog to confirm the delete action. The chosen integration will be deleted and will no longer be displayed in the Manage Integration Settings screen.
