USTC Payment Portal

This package makes SOAP requests to the pay.gov hosted collection pages service.

The application is intended to handle API requests from USTC applications and then make requests to Pay.gov on its behalf.

Workflow

1. An application makes a request to initiate a transaction the Payment Portal.
2. The portal then performs a startOnlineCollection request to Pay.gov with the transaction information.
3. Pay.gov responds with a token, which the portal uses to generate a redirect URL to Pay.gov to enter in payment information.
4. The token and URL are returned to the original App, which stores the token and forwards the user to the redirect URL.
5. The user enters their payment information or cancels, which sends them back to the success or cancel URL specified in the original request.
6. Once back on the originating app, the app makes another request to the Payment Portal to process the transaction.
7. The payment portal calls Pay.gov to perform a completeOnlineCollection with the token.
8. Pay.gov responds with a Tracking ID, which is relayed back to the App via the Portal.
