I have a web app where my customers have Payflow pro and payments pro merchant accounts and they can import cards to my app. I need an api to verify if the cards mentioned are present under that account. They will be giving me their login credentials while setting up the integration and PNREF codes for importing the cards. I need to verify if the PNREF mentioned is under my customers' merchant account.Is there an API i can call with my customer's credentials and the PNREF mentioned to verify it is under his account?
