The Project creates at its site a payment button with a link to the Project's payment page at the System site.
After pressing the Pay button the user is automatically redirected to the payment page on the System site, where he/she can choose a payment mode and enter the missing data, if it's needed.
Workflow in case of Simplified Integration
1. Project transfers data to the System. The System creates an invoice.
2. The System notifies the Project via e-mail – Payment notification.
The System offers to secure payments with additional requests. But all of them require modifications on the Project side: the handler on the special URL is needed.
1. User or Order ID verification - ensuring that the invoice and subsequent payment are tied to the correct account in the Project system.
3. Redirect users to the payment result page on the Project site.
