GenerateQR

Cortina DQR uses the GenerateQRcommand to notify the integrator about the consumer's product selection in order for him to send the QR generation details.
The command includes the transaction Id identification (Generated in /StartSession), required Amount, merchant, and Machine details (and more).
The Cortina payment provider shall validate the information and respond with the Dynamic QR information to be displayed on the Nayax device accordingly.

This command is essential for proceeding to authorization process.
