I’m not sure why this isn’t in the Google domains library or help.
How do I bulk update all my google domains to a new credit card?
Google domains official answer was:
Thank you for contacting Google Domains.
I can see here that you're trying to update your payment method for your domain names registered. Due to security reasons we can't make changes on a users behalf. I'll be glad to guide you through the process step-by-step. It's great that you reached out on how you can update your payment in bulk. Please follow the steps below:
Log in to Google Domains.
Click on the All check box for the Name under My Domains.
Click the Renew Domain on the upper right.
Click Turn off auto-renew.
After turning it off, click the All check box again.
Click Renew Domain.
Click Turn on auto-renew and you'll be asked to input the card you'll be using.
