Servers & Network
Server domains and IP addresses by environment for Easy Cash (Open Banking) integration. Refer to the information below when configuring your firewall.
The Easy Cash Direct Debit (Open Banking) API is called directly from your server in JSON format.
Account management, transfer service, and inquiry service APIs all use the same server environment.
| Environment | Domain | IP Address | Protocol |
|---|---|---|---|
| Sandbox | tbnpay.settlebank.co.kr | 61.252.169.31 | HTTPS (TCP/443) |
| Production Primary | npay.settlebank.co.kr | 61.252.169.27 | HTTPS (TCP/443) |
| Production Secondary | npay.settlebank.co.kr | 14.34.14.24 | HTTPS (TCP/443) |
NOTE
IDC redundancy configuration
• The Hecto Financial Easy Cash Direct Debit system uses a Primary and Secondary data center for redundancy.
• In the event of a Primary center failure, traffic automatically switches to the Secondary center. Allow both Primary and Secondary IPs in your firewall settings.
• DNS Lookup connections are recommended — switchover is handled automatically. (Hardcoding IPs in the hosts file will prevent automatic failover.)
