Delete payment source for individual customers so that they cannot create more subscription
If you want to restrict an individual customer to create a subscription and want to delete the payment source. You can choose to remove the customer's payment source from Chargebee UI or via API.
1. To delete the payment sources from the customer page
Navigate to the Customers tab->Load the customer and delete the payment source
Click this link - Delete payment source Via API to know more.
In Chargebee, we can’t restrict any individual customer from the gateway when their payment details are present.
However, you can check with the associated payment gateway if there is an option to restrict that specific account.
