Payment by the button in the mobile app (InApp)
Apple Pay
When the token payment is executing by button in a mobile app, the following actions are performed:
The buyer selects the product or service in the store mobile app and presses the pay button.
An encrypted packet with payment data and a token is generated by accessing the SDK of the respective provider: Apple Pay API.
The SDK of Apple Pay conducts the required payment authorization by the buyer on the mobile device (PIN / fingerprint).
The encrypted packet with payment data and a token is transferred to the TokenPay payment service on the side of IPS Assist.
