Hi guys,
In our app it is possible to make a payment as anonymous user.
This anonymous user creates a payment and response object with a POST request. And goes further to the payment environment. After payment is (not) done, he will be redirect to a URL back to the app. With rest services I fill the response whether the payment is made or not (GET). And after the user has made the payment there will be created an account etc.
Now I want to know how to set up this the right and safe, so I can retrieve the payment, response object when the user is returning to the app and go further with the other processes.
I think the question comes to this, how can I retrieve the same anonoymous user in the return url, so I can retrieve the associated payment and response?
