Decline code 0.02 - Order Expired
Right now the PayPal order is created for each successful init request of the PayPal button. Although, there are cases when a customer decides to pay via card or chooses another alternative payment method.
To easily detect the occasion when the order was created only because of the PayPal button initialization and there were no attempts to try to pay via PayPal we have added the decline code 0.02 - Order Expired.
The PayPal button is active for one hour after initialization. In case there were no attempts to pay via PayPal during this time period, after one hour you would receive a declined order with the 0.02 decline code.
Also, kindly find the example of how such order looks in our admin panel - HUB.
