Special Fields

Show QR Code on Payment Page - a QR code will be displayed for quick payment access for the customer

Payment Method - select the currency/network for receiving funds

- a confirmed transaction means it has been included in a block and, therefore, in the blockchain. It has been verified and recorded, the payment has been processed, and it cannot be changed or canceled. To be considered legitimate, the operation must receive a certain number of confirmations. Each new confirmation exponentially reduces the risk of the transaction being reversed.

Continuing the Setup

Next, configure the merchant by following the general setup instructions.
