We recommend whitelisting the domains rather than IP Address. Please whitelist sandbox.api.visa.com domain on your server accordingly.
Would prefer to whitelist domain also but Kubernetes Network Policies support whitelisting by IP CIDR ranges only. Is there a range we could use?
I'm happy to help you answer this question. I'll get back to you soon on this once I find out.
Here are the Sandbox external IPs that you can use. Please note, these are only sandbox IPs. you'll need to whitelist the other environments as you are ready to go to production.
Please let us know if there's anything else we can do to help.
That's great, we have configured these in our egress policy.
Looking ahead we will have the same question for Production so wondering whether Production IP addresses will be available or whether we need to pursue a DNS whitelist solution further?
That's another good question. Please allow me to take a look and I'll be happy to get back to you soon on this.
