Reference: Hosts and Protocols

Various services work together to deliver the full Workday Peakon Employee Voice experience. This topic lists the hosts and protocols that you need for configuring firewalls and proxies to enable access.

Protocols

All communication takes place over TLS on port 443. The underlying protocols are HTTPS and WSS.

Hosts

Note: Use the hosting region that matches your location: EU, US, or UK. Check the relevant information for your tenant’s hosting region to ensure proper setup and support.

Hosts and Details
Workday Integration
Traffic routes through the Workday private network, eliminating the need to track Peakon public IP addresses manually.
Review the security configuration for your Workday Peakon integration system user. Ensure your authentication policy permits
Workday Internal
traffic if you use authentication policies to restrict access for your integration system user. The Session IP Address displays as
Workday Internal
in the Signon History for Person report once enabled. If you do not use IP-based restrictions in your authentication policies, no action is required.
