ConnectPay validates data and creates Payment Order resource. In API Response will be property _links.scaRedirect.href with URL to ConnectPay Auth webapp where to redirect PSU for payment authorization
TPP redirects Agent to above mentioned link.
Please always use full redirect, so PSU would be able to see ConnectPay URL in browser window. Embeding ConnectPay webapp into TPP interface via iFrame or other options is not allowed.
PSU will login with own ConnectPay’s credentials and confirm or reject payment.
Auth webapp will redirect browser back to TPP website using RedirectUrl that TPP provided in Initialize Payment request.
If, after rerdirection back, URL will have query parameter error – it means something went wrong with Auth request. Find and fix cause of error and initialize new payment.
