Before you begin installing VMware Tunnel, you have to ensure that the API and AWCM are installed correctly, running, and communicating with the Workspace ONE UEM without any errors. Read through the following topic to configure the AWCM server.

Important:  If you are an on-premises customer, do not configure VMware Tunnel at the Global organization group level. Configure VMware Tunnel at the Company level or Customer type organization group. The REST API key can only be generated at a Customer type organization group.


  1. Navigate to Groups & Settings > All Settings > System > Advanced > API > REST API and select the Override radio button.
  2. Ensure that the Enable API Access check box is selected and an API Key is displayed in the text box.
  3. Select Save.
