PayPal return url

Hello!
While tinkering with the website settings in the paypal account, I see that they require that the user is taken to the website with some text info and the order details.
What is the return url the user should be redirected to?

Or should I turn off the Auto return function?
“Note: Turning OFF Auto Return will disable Payment Data Transfer feature.”
I see that for an offline payment, the final url is https://mydomain.ro/finalizare-comands-curs/comanda-primita/10612/?key=ORDER605E10128B654

Thank you!
