How can I fix the IP address an API sees from my AWS Kubernetes pods

Question

I have a Drupal site running on an AWS EKS Kubernetes cluster.

But I need to access a 3rd party API that requires an IP whitelist, however when I run curl ifconfig.io I get different results each day. Is there a way to fix this. My pod's Service domain resolves to 3 IPs however none of these are what a 3rd party sees when I try to access them. Also does anyone know what this IP is called ? Is this the Source IP? Many thanks

I think that a VPC in which your cluster is running needs to have an Internet Gateway with a static Elastic IP attached to it.
