Caution! For standard workflows you don't need to use any of the following methods. They serve special purposes where you need more control.

• paymentForm.payerDataChanged(customerData)

paymentForm.processPaymentData(totalGross, currency, success, error)

processPaymentData sends the payment data to the PSP and returns the processed data or an error. This enables you to do further checks on this data, e.g. BIN checks (CC), bank country (Debit). All PSPs which support PSD2 can be used with this method. Please note that this method is not meant to validate payment data!
