Hello,
I hope you are doing well.
Our third-party provider is only able to whitelist a single IP address.
I understand that Railway has migrated to HA Static IPs, which now provide three IP addresses for redundancy. However, our provider is unable to whitelist all three IPs and can only support one.
Would it be possible to make an exception for our project, or is there any alternative solution that would allow us to continue using a single static IP?
I would greatly appreciate any advice or assistance you can provide.
Thank you in advance.

HA Static IPs assign three addresses with traffic load balanced across them, and there is no option to pin outbound traffic to a single IP. All three addresses need to be allowlisted on the receiving end. If your provider truly cannot accept more than one entry, you would need to route traffic through your own proxy (e.g. a SOCKS/HTTP forward proxy on a fixed-IP VPS) so that only that single proxy IP appears to the downstream provider.

Can you ellobrate more on what you meant by "your own proxy (e.g. a SOCKS/HTTP forward proxy on a fixed-IP VPS) so that only that single proxy IP appears to the downstream provider"

The bot means that you should have a proxy (small vps) which all traffic for your service runs through and therefore ends up on the same, single IP which you can allowlist, because unfortunately it isn't possible to change the static HA IPs into a single IP (that defeats the point of HA), and the old static IP feature is likely being deprecated at some point in the future.
