Hi everyone,
In October of 2022, Stripe published an updated list of IP addresses that api.stripe.com may resolve at https://stripe.com/docs/ips.
We intend to use some of those new IP addresses as of May 17, 2023, and ask that you ensure that your firewall egress rules will permit requests to api.stripe.com through any of the published IP addresses.
As a reminder, while we publish a list of fixed IP addresses for api.stripe.com, you must only send API traffic to the IP addresses returned by looking up api.stripe.com through DNS. This IP address list is provided solely to help you set up egress firewall rules, if needed.
