Namespace NFX.Web.Pay

Classes

Address

Primitive (maybe temporary) implementation of IAddress

ConfigBasedCurrencyMarket

Provides rate conversion services based on an APP config file

PaymentException

General NFX payment system specific exception

PaySession

Represents session of PaySystem. All PaySystem operation requires session as mandatory parameter

Base class for IPaySystemImplementation implementation. Instances of descendants of this class is typically created and configured in PaySystemStarter class. Then particular pay system can be obtained from PaySystem.Instances[PAY_SYSTEM_NAME] indexer

PaySystemHost

PaySystemStarter

Represents a starter that launches payment systems on startup

PaySystemWithStaticFees

PayWebTerminal

Transaction

Represents an abstraction of financial operation performed with pay system

Transaction.Operation

Structs

Account

Represents an account data vector that is - type of account identity (i.e. 'customer'), identity id (i.e. customer number '125') and account id within this identity (i.e. ref to customer #125 card '223322.....'). May also represent temporary web terminal token generated by IWebPayTerminal in which case IsWebTerminalToken = true

Interfaces

IActualAccountData

Represents actual data for supplied account object. Data represented by this interface is ALWAYS TRANSITIVE in memory as some fields are either never stored permanently (i.e. CVC) or ciphered in the store (account number)

IAddress

Represents address

ICurrencyMarket

Represents a market that can convert buy/sell currencies

ICurrencyMarketImplementation

IPaySessionContext

Denotes a context of transaction execution. Can be used to provide additional information

IPaySystem

Describes an entity that can perform pay functions (i.e. charge, transfer)

IPaySystemHost

Represents a process-global entity that resolves account handle into actual account data and fetches existing transactions. This design provides an indirection level between pay systems (like Stripe, PayPal, Bank etc.) and particular application data store implementation as it decouples system-internal formats of transaction and account storage from provider-internal data (i.e. PayPal payment token string). The instance of implementor is a singleton accessible via PaySystem.PaySystemHost

IPaySystemHostImplementation

Denotes an implementation of IPaySystemHost

IPaySystemImplementation

Describes an entity that can perform pay functions with several usefull interfaces in NFX style

IPaySystemWithFee

Pay system with fee

IPayWebTerminal

Represents a web terminal for pay systems that tokenize sensitive CC data via a call to provider so that actual CC numbers never touch our servers in a plain form, instead tokens/nonces are supplied back by the provider tokenizer. This is needed for PCI compliance.
