Servers & Network
Server domains and IP addresses by environment for Cash Receipt integration. Refer to the information below when configuring your firewall.
The Cash Receipt API uses two domains. Most APIs use the primary domain, while certain inquiry APIs use domain2. The primary domain handles real-time operations such as registration, cancellation, and status inquiry, while domain2 serves the inquiry APIs that check NTS processing results in batch (issuance error list inquiry and reprocessing result list inquiry) — the domains are separated according to business flow.
API (domain)

| Environment | Domain | IP Address | Protocol |
|---|---|---|---|
| Sandbox | tb-nspay.settlebank.co.kr | 61.252.169.42 | HTTPS(TCP/443) |
| Production | nspay.settlebank.co.kr | 14.34.14.21 (Main) 61.252.169.53 (DR) | HTTPS(TCP/443) |
NOTE
IDC Redundancy Configuration
• The Hecto Financial PG system operates with Main and DR (Disaster Recovery) data centers for redundancy.
• In the event of a Main center failure, traffic automatically switches to DR. Allow both Main and DR IPs in your firewall rules for the Production environment.
• DNS Lookup connection is recommended — failover is handled automatically.
