I’m hitting a wall with a Data Action that calls our internal AWS API. When I test the action from the Genesys Cloud Admin UI (the ‘Test’ tab), it works perfectly and returns a 200 OK.
However, when the action is called from an Architect flow on an active call (running on our BYOC Premises Edge servers), it fails with a 403 Forbidden.
Our AWS API uses IP-based whitelisting. I’ve already whitelisted the Genesys Cloud IP ranges for our region. Why would the ‘Test’ button work but the ‘Live’ flow fail? Does the Edge server use a different outbound IP address than the standard Genesys Cloud services?
As an AppFoundry partner, we see this all the time with customers using on-prem Edge servers. When you click ‘Test’ in the UI, the request is actually sent from the Genesys Cloud backend servers (in the AWS cloud). When an Architect flow runs on a Premises Edge, the request is sent directly from the Edge appliance itself.
You need to whitelist the Public IP address of your Edge servers, not just the Genesys Cloud CIDR blocks. Your Edge appliances are likely sitting behind a NAT, so check what IP they are egressing as and add that to your AWS whitelist.
Kaz is correct. This is a classic ‘Premises’ vs ‘Cloud’ networking issue. If you’re in Germany (like us) and have strict GDPR requirements, you might also have a local firewall on your Edge subnet that’s blocking the outbound 443 request to AWS. Ensure your Edge servers have ‘Internet Egress’ for the specific AWS API endpoint you’re trying to hit.
I’ve load-tested these scenarios at scale. One thing to watch out for: if you have a cluster of Edge servers, make sure all of them are whitelisted. If you only whitelist Edge #1, your Data Actions will fail intermittently whenever a call is handled by Edge #2 or #3.
Also, check your ‘Proxy’ settings on the Edge. If the Edge is configured to use an outbound proxy for all traffic, your AWS API will see the Proxy’s IP address, not the Edge’s IP.
