captureMandate.requestSaveCredentials

This feature enables you to display a consent option in the

Unified Checkout

UI for the cardholder to save their payment details for future use.

When you use this field without using the complete mandate, the transient token payload includes the

consumerPreference.saveCard

field with the value set to

true

when the cardholder has checked to save the payment information for future purchases:

"captureMandate" : {
      "requestSaveCredentials": true
}
