# Card Stored Credential

Provides additional details to process a payment using a `card` that has been stored or is intended to be stored (also referred to as stored_credential or card-on-file). Parameter compatibility: `payment_type=ONE_TIME` is compatible only with `payment_initiator=CUSTOMER`. `usage=FIRST` is compatible only with `payment_initiator=CUSTOMER`. `previous_transaction_reference` or `previous_network_transaction_reference` is compatible only with `payment_initiator=MERCHANT`. Only one of the parameters - `previous_transaction_reference` and `previous_network_transaction_reference` - can be present in the request.
