Hello, according to some documentation I should receive a response from external applications when returning to my site.
The process is as follows:
mywebsite.com > pageadofinalization.com > mywebsite.com/success



How on the Success page can I catch the response sent to me and use it to, for example, not send an order confirmation. I will add that I can indicate where this answer should land, it can also be mywebsite/api/getdata. But I still don't know how to receive it right from the page.
