Conceptual Architecture

Payment Flow Overview

Authorize (reserve funds)
  -> Capture (collect on shipment)
    -> Refund (return funds, full or partial)
  -> Void (cancel before capture)

This authorize-capture-refund lifecycle applies to both B2C and B2B. Some flows combine authorize + capture into a single "sale" operation.

Salesforce Payments (Native)

Multi-processor support: Salesforce Payments integrates with Stripe, Adyen, PayPal, and other processors. Configuration is unified within Salesforce Commerce setup.

Feature	Detail
Payment methods	Cards, Apple Pay, Google Pay, ACH, SEPA, local methods
Saved methods	Tokenized cards for returning customers
Fraud detection	Via configured processor (Stripe Radar, Adyen risk)
3DS / SCA	Built-in support through processor
Dispute management	Chargeback handling and evidence submission
Multi-currency	Configured per processor account

B2C Payment Processor Architecture

Cartridge-based integration:

• Payment processors packaged as SFCC cartridges (int_stripe, int_adyen, int_paypal, int_cybersource)
• Cartridge overlays base commerce cartridge
• Configuration in Business Manager: credentials, endpoints, payment method assignment
• Site-specific processor configuration per locale

Payment Hook Points:

Hook	Purpose
Authorize	Reserve funds on payment method
Capture	Capture authorized amount (full or partial)
Refund	Return funds to customer
Void	Cancel authorization before capture
Verify	Validate payment method ($0 auth)

Server-side scripts (authorize.js, capture.js, refund.js, void.js) receive basket/order, payment instrument, and amount; return {authorized, error, errorMessage}.

Client-side integration:

• Tokenization via processor SDK (Stripe Elements, Adyen Drop-in)
• Hosted payment fields (iframe) for PCI compliance
• Token submitted to server instead of raw card data

B2B Payment Adapter Architecture

Apex PaymentGatewayAdapter interface:

• Implement in custom Apex class with methods: authorize, capture, refund, sale
• Return PaymentGatewayResponse with status, transaction ID, errors
• Register adapter in Setup > Payment Gateways

// Pattern: B2B PaymentGatewayAdapter skeleton
public class MyAdapter implements PaymentGatewayAdapter {
    // Fetch live docs for PaymentGatewayAdapter interface
    // Implement: authorize, capture, refund
}

B2B Payment Method Types:

Method	Notes
Credit / debit card	Via PaymentGatewayAdapter
Purchase order (PO)	PO number required at checkout
Net terms	Net 30, Net 60 per account
ACH / bank transfer	For B2B bank payments
Invoice	Payment against generated invoice

B2B-specific considerations:

• Credit limit enforcement at checkout
• Integration with approval workflows for high-value orders
• Multiple payment methods per order (split payment)

PCI Compliance

Tokenization Principle:

• Never store or transmit raw card numbers through merchant servers
• Payment processor tokens replace card data; tokens stored in Salesforce (safe)
• Processor maintains secure vault with actual card data

SAQ-A Compliance:

Requirement	Implementation
Card data never touches merchant servers	Use hosted payment fields (iframe)
Client-side tokenization only	Processor JS SDK tokenizes before form submit
Server receives tokens only	No raw card data in server logs or database
Processor handles PCI DSS Level 1	Stripe Elements, Adyen Drop-in provide compliant fields

3D Secure / SCA

3DS2 Authentication Flow:

Payment submitted
  -> Processor risk assessment
    -> Frictionless (low risk): instant approval
    -> Challenge (high risk): redirect/iframe to bank
      -> Customer authenticates (password, biometric, OTP)
        -> Success: proceed with authorization
        -> Failure: decline payment

SCA Requirements (European Transactions):

• Strong Customer Authentication required for European cards/merchants
• Exemptions: low-value (<30 EUR), recurring, trusted beneficiaries
• 3DS2 is primary SCA compliance method
• Successful 3DS2 shifts liability to card issuer

Code Examples

// Pattern: B2C payment authorization hook
// Fetch live docs for SFCC PaymentProcessor scripts
// function authorize(order, paymentInstrument, amount)
//   -> call processor API -> return {authorized, error}

// Pattern: B2B gateway registration
// Fetch live docs for PaymentGateway setup
// Setup > Payment Gateways > register adapter class
// Store API keys in Named Credentials, not code

Best Practices

General Payment Security

• Always tokenize; never handle or store raw card data
• Use hosted payment fields (processor iframe) for SAQ-A eligibility
• Store API keys in Named Credentials or Custom Settings, never in code
• Implement webhook signature verification for async payment events

B2C Cartridge Development

• Follow standard cartridge structure for payment scripts
• Return proper error messages for failed authorizations
• Always capture and store processor transaction IDs
• Support partial capture (split shipments) and partial refund (returns)

B2B Payment Integration

• Support purchase orders with net payment terms for B2B buyers
• Validate against account credit limits before authorization
• Integrate payment with B2B approval workflows
• Enable ACH/bank transfer methods for B2B transactions

3D Secure

• Request 3DS2 authentication for all card payments
• Handle SCA exemptions properly (recurring, low-value)
• Provide good UX for challenge flows (iframe preferred over redirect)
• Verify 3DS authentication status and liability shift before proceeding
