I am integrating PayPal into my system, and baffled with one question.
Basically PayPal is an Aggregator for Payment methods, hence you can add multiple cards/accounts for payment procedures inside my website. However I am wondering does PayPal move on to next payment methods of the account if the default (chosen by user) one is failed?
Reason why I am asking is that PayPal SDK for vaulting, allows user to choose only one method from popup. (See below image)
If my user chooses only for example CREDIT UNION 1 and later on it fails to charge money. Will PayPal automatically proceed to charge from Visa listed bellow?
