If you are a Google Domain admin, you can utilize domain groups to control access to your apps.
You may need to first configure your Google domain to enable API access. To do so,
- Log in to the admin account for your Google domain (or G-Suite domain)
- Select Security. If you do not see Security listed, select More controls and then select Security from the options shown in the gray box.
- Select API reference, and then select the checkbox to Enable API access.
- Save your changes.
You will then need to add your Google Domain as a domain auth provider in your AppSheet account.
