To be able to collect payment from PayPay user’s wallet, you need to obtain user’s authorization explicitly.
Acquiring user authorization is achieved through a simple web redirect flow, similar with OAuth/OpenID Connect style WebView authentication & authorization flow.
Upon successful authorization, a user authorization id will be issued to you per user. You should store this id in your backend and link it to your internal user. Please ensure this user authorization id is not stored on the client side. This id will be used as the user identifier in the Payment, Cashback and Topup requests.
