Profile – Payment
The Payment tab is where you go to add/remove payment profiles:
To add a new credit card, click on the Add Payment Profile button, and enter your credit card info, and then Save. If it is the first/only profile, it will be set as default, if there are already existing profiles, it will be set as secondary profile, which you can make default by clicking the “set as default” link. It is highly recommended to delete old/expired cards and keep your preferred active one as default.
Please see the following knowledge base articles that discuss the other three tabs:
