The AEM Cloud Integration That Wouldn’t Work—Until I Enabled Dedicated Egress IP

A while back, I was working on an integration where AEM Cloud had to talk to a client’s third-party API. Nothing unusual until I hit a wall.

🧩 The Problem

The API was locked down with strict IP allowlisting (fair enough, security first). But here’s the catch: AEM as a Cloud Service doesn’t use fixed IPs, it uses shared, dynamic egress IPs. And dynamic IPs can’t be allowlisted. Classic cloud pain.

At one point, I briefly considered whether the client’s API could trust requests based on our domain name instead of a static IP. But that idea didn’t go far—the client’s team was clear: they needed strict IP allowlisting for security, no exceptions. But for backend-to-backend calls, domain-based trust just doesn’t cut it. So i had to find another way.

🔐 The Fix

That’s when i looked into Adobe’s Dedicated Egress IP. It gives your AEM environment a static outbound IP—exactly what the client’s API needed for allowlisting. I got it enabled, shared the IP, and finally cleared that security gate.

🛠️ But Then Came the Twist

Even with the dedicated egress IP enabled, the API calls were still failing.

Digging deeper, I realized the current HTTP client library didn’t support the proxy configurations required by Dedicated Egress IP.

Based on the official Adobe guide, i needed to switch to a compatible HTTP client that supports proxy configurations necessary for the dedicated egress IP to work properly. Specifically, I had to use the Java 11 HttpClient, which has built-in support for system proxy settings. After refactoring our service to use this HTTP client, I finally got everything working smoothly, with outbound requests properly routed through the dedicated egress IP.

💡 What I Learned

• If you're integrating secure APIs with AEM Cloud, Dedicated Egress IP can be a lifesaver.
• Don’t overlook your HTTP client—it must support proxy settings to work with Adobe’s networking setup.
• And lastly, working closely with the client’s API team made all the difference. Security was their top concern, and I respected that while finding a workable solution.

I hope this story gives you some insights if you're facing similar hurdles with AEM Cloud. The Dedicated Egress IP feature really helped resolve our integration issues, and I believe it could do the same for you. I’ve always found that Adobe’s documentation and communities hold the answers — it just takes some persistence and a curious mindset to uncover them!
