I was using PHP code (below) but stopped to work. Did Paypal changed something about. It does not work anylonger.
print_r($res) gives this:
Invalid URL The requested URL "[no URL]", is invalid. Reference #9.67ac1002.1539939948.1d3bb0b6
The payment to Paypal works OK, Paypal returns to successfull page URL OK.
