How to implement a return to the blockonomics payment window? If I leave the payment window and click Purchase again, a new order is created with a new BTC address.
I mean, if the buyer left the payment page (the one with bitcoin address, payment amount, payment timer), then the next time he clicks “Purchase” in the cart – a new “Pending” is created with a new address, amount and timer. But the previous payment window should open. How to fix it?

I followed the tutorial and set it up, but I get an error.
