Use Cases

• Merchants managing their own card list and payment interaction, without needing the PingPong checkout page
• Merchants maintaining token-to-card mapping locally

Prerequisites

• Completed the CardOnFile first-time binding flow and obtained a card token
• Know whether bizType=CardOnFile was passed during initial binding

Interaction Flow

Integration Steps

1. Client places order

   Customer initiates order creation on merchant platform

2. Merchant server requests order and payment

   Call Place order and pay API

   • Pass token
   • If bizType=CardOnFile was passed when creating token, then every subsequent transaction using token needs to be sent

3. Order and pay API synchronously responds with payment result

   Place order and pay API will immediately return processing result

4. Async notification pushes final result

   System will push final payment result through async notification mechanism, see Async Notification for details
