Site Not Reachable from Workfront Fusion to Apigee After IP Whitelisting

Hi Team,

We're facing connectivity issues in Workfront Fusion when connecting to a client's Apigee endpoint for SAP integration using the HTTP module, despite sharing the official Fusion IP addresses list for whitelisting.

Key Findings:

• Requests from Fusion hit Apigee showing source IP 52.123.145.90 in logs

• Whitelisting this specific IP in Apigee immediately resolves the issue and returns successful responses

• Problem: 52.123.145.90 is NOT listed in the official documentation

  • https://experienceleague.adobe.com/en/docs/workfront-fusion/using/set-up-and-manage-fusion/set-up-and-manage-orgs-and-teams/set-up-orgs-teams-and-users/set-up-ip-addresses-for-fusion#add-ip-addresses-and-domains-for-your-datacenter

Questions:

1. Does Fusion use additional cluster-specific IPs beyond the documented list?

2. How to get the complete IP range for our specific Fusion datacenter/region?
