UI Callback

The UI Callback response is sent to a URL that is passed in redirectUrl along with the request.
The value of the redirectMode can be either REDIRECT or POST to get a UI callback.

🚧
For redirectMode as POST, Merchant's URL should be capable of handling the POST method and accepting the Form Post Response. Once the Form Post response is received, merchant can check the status in their backend server and accordingly redirect the user to the respective payment status page.
