decode

In entry code scenarios, Alipay+ stores the payment information as a code value. The Alipay+ client SDK calls the decode API to send the code value to the Mobile Payment Provider (MPP). The MPP can then call the server API userInitiatedPay to decode the code value and obtain the payment information.

Note: For entry codes to work, the MPP must implement the decode API.
