Cashback usage setting (1.0)

The PayPay Open Payment API requires that you use TLS 1.2 or higher as a security measure. Note that you cannot connect with TLS1.0 and TLS1.1.

To start utilizing our Open Payment API platform, at first the business needs to be onboarded as a PayPay merchant.

This process usually consists of information collection, manual verification, contract confirmation and credentials issuance.

After becoming a merchant on PayPay, the following items would be setup for the client:

• api key and secret
• webhook endpoints
• client IP whitelist

This setup can be managed using our merchant panel/ getting in touch with the sales representative.

To be able to collect payment from PayPay user’s wallet, you need to obtain user’s authorization explicitly.

Acquiring user authorization can be achieved using our simple account linking flow here.

Everything related to OPA API Authorization is described here.
