When Payt initiates a connection to your systems (webhook deliveries and other outbound traffic), requests originate from a fixed set of IP addresses. If your firewall restricts inbound traffic, allowlist these addresses.

​
Outbound IP addresses

These IP addresses are subject to change. Avoid hard-coding them in your application. Reference this page instead, and where possible allowlist by hostname rather than by fixed IP.
This page is the single source for Payt’s IP addresses. Other pages link here rather than repeating the values.
