Direct API Introduction

Merchants want to display payment methods to users and pay at their own cash registers. PayerMax provides pure API (Direct API) access. The biggest difference from the cash register model is that users do not need to jump to the PayerMax page.

1. Applicability

• Merchants want to control the cash register themselves and complete payment interactions on their own pages to the greatest extent possible;

• Merchants have strong development capabilities, new payment methods need to be connected, and development and coordination work needs to be done.

2. User Flow

2.1 Card Payment

Merchants build their own checkout counters, and users choose card payment. After filling in the card information on the page and confirming the payment, the merchant calls PayerMax to make the payment.

2.2 Wallet Payment

The merchant builds the cashier by himself, the user selects the payment method to pay, the merchant pulls up the wallet payment page returned by PayerMax, and the user completes the payment on the wallet page. (The merchant can also implement this type of interaction by specifying the payment method in the cashier mode)
