What are the static outbound IP addresses for FusionAuth Cloud?
-
We need to configure IP allowlists in our downstream services (email provider, webhooks, etc.) to accept traffic originating from our FusionAuth Cloud instance.
Our service requires that we whitelist the specific source IP addresses that will be making outbound requests. Does FusionAuth Cloud use static outbound IP addresses, and if so, what are they for each region?
Additionally:
- Are these IPs guaranteed to remain stable over time?
- If they ever change, will FusionAuth notify customers in advance?
-
Yes, FusionAuth Cloud uses static outbound IP addresses that you can whitelist in your downstream services. The specific IPs depend on your deployment's region.
These IP addresses are static and will not change under normal circumstances. If FusionAuth ever needs to modify or add to these addresses, customers will receive advance notification.
To obtain the specific outbound IPs for your region, you'll need to open a support ticket through the FusionAuth Account portal with your deployment name and details.
Important Notes:
- New deployments receive static outbound IPs by default. If you have an existing deployment created before static IPs were standard, you may need to request them via support ticket.
- The provided IP addresses are intended only for allow-listing outbound traffic (such as SMTP services, webhooks, LDAP connectors, etc.). These IPs should not be used to make inbound API calls, as they won't respond to such requests.
- Static IPs are available for all FusionAuth Cloud deployments, including both standard and High Availability (HA) configurations.
