Domains

The Domains module is a read-only directory of all checkout domains registered in Payment Nexus. A domain is a fully qualified domain name (FQDN) that routes incoming checkout traffic to a specific tenant. Domains are managed through each tenant's own configuration — this module provides a system-wide view across all tenants.

Production vs Sandbox

Each domain is classified as either production or sandbox:

• Production — Handles live transactions.
• Sandbox — Used for testing and integration development. Can optionally be restricted to a whitelist of IP addresses so only designated test systems can reach it.

To add, edit, or remove domains for a tenant, navigate to that tenant's record and use the Domains section there.
