Using Payment Adapter for Self Service > Make a Payment

Good morning.

We are working on a project that will be using Payment Adapter for student self service payment. When the payment is completed on the Third Party Hosted Payment site, the page is redirected to "WEBLIB_SCC_HPTP.SCC_HPAY_THRD_PRTY.FieldFormula.IScript_Successful_Payment_TP"

In our case, once the payment is completed without error on the vendor site, the payment is considered captured regardless if the student clicks Cancel or Submit on the above page. Is it possible or has anybody able to bypass this page and apply the payment to the student account?

Appreciate any insights and suggestions.
