Opening payment page requires you to call the process SDK API with process payload as input. It should not be called on an HyperSDK instance which has not been initiated. To verify if an instance is initiated, kindly refer to check SDK isInitialised section under code snippets
.
Once the payment page is opened, users can proceed with the transactions.
Pass the sdk_payload from the Session API
(s2s backend call) response as the processPayload.
