Card Type Transaction Flow for Mobile SDK

4.1 Onboarding Process

The merchant onboarding process follows the sequence below:

1. Merchants are onboarded in the Credit Plus application first
2. After onboarding on the Credit Plus platform, merchants are then onboarded on the CyberSource/MPGS platform
3. Once the merchant is onboarded on both Credit Plus and MPGS/CyberSource platforms, the operations user will onboard the merchant in the WL PG (White Label Payment Gateway)

4.2 WL PG Terminal Configuration

The Payment Gateway will be able to process SDK transactions once the following fields are enabled at the terminal module:

• Enable SDK Payment Instruments at the Terminal configuration module
  • Enable Credit and Debit payment instruments

4.3 SDK Transaction Flow - Card Type Transactions

The following illustrates the card-based transaction flow in the mobile SDK environment:

Transaction Flow Steps:

1. Customer Initiates Purchase
   • Customer visits the merchant mobile application
   • Customer adds items to cart and clicks the buy/checkout option
2. Merchant Invokes SDK
   • Merchant mobile application invokes the WLPG SDK to initiate the transaction with WLPG
   • Note: Details on invoking SDK methods will be covered in the integration implementation document
3. SDK Initiates Payment
   • WLPG SDK invokes the initiatePayment API call to WLPG for initiating the transaction
4. Payment Processing
   • WLPG processes the transaction with authentication and authorization
   • WLPG sends the transaction status back to the WLPG SDK
5. Transaction Status Response
   • WLPG SDK sends the final transaction status to the merchant application
   • Merchant application displays the transaction result to the customer
