My app uses the abandoned checkout webhook so that the user can be notified when someone proceeds to checkout and then leaves. However, I noticed that I got a bunch of notification (response) when I clicked "checkout" once as the pic shows. What possible reasons could lead to this situation? Another question that I have is, from my understanding, this API is triggered when someone enters payment page and exits, but it seems to me that it is triggered when someone "enters" payment page.
Can you elaborate more on the payment method gateway question? I am not the owner of the project so I could not permit you to access it but thanks so much for helping!
