How to connect with a commercial bank

This is used exclusively for developers to easily connect to the API of commercial banks. The first step is to send information to request a QR String from the bank. After that, you can connect the Socket to wait for the payment results from the bank.

How to create a QR string with bank

Creating a QR string for payment can be done using the link and method below

    curl --location 'https://payment-gateway.lailaolab.com/v1/api/payment/generate-bcel-qr?amount=$AMOUNT&description=$DESCRIPTION' \

    --header 'Content-Type: application/x-www-form-urlencoded' \
    --data-urlencode 'amount=$AMOUNT' \
    --data-urlencode 'description=$DESCRIPTION'
