I wanted to accept credit card payments and therefore I setup a Payflow account. It is currently linked to my eBay account. How can I remove the same from my eBay account?
It is not possible to remove the Payflow account linked with your eBay account. The same Payflow can be associated with a different eBay account but it cannot be unlinked from an account.
If you don't want to accept credit card payments, you just need to remove IntegratedMerchantCreditCard payment method from your listings and stop adding this payment method in their future listings.
