Once the Hypercheckout screen is opened, your users can proceed with the transactions. Opening Hypercheckout requires a Server-to-Server request from Merchant to Juspay. The response of this should be forwarded to the Hypercheckout SDK in order to open the payment screen.

This step should be done only once the final payable amount is available

You may also configure the test credentials of the gateway and use the respective test cards for completing the transaction journey.
