Where to get IP information for an instance for outbound calls to share with API provider?

Nisar3 · yesterday

The owner of one the APIs that our servicenow instance consumes is asking us to share IP details because they are enabling IP Whitelisting at their end. Which IPs should I share? Where will I get that details from?

And wouldn't the IP depend on the user's location who is currently logged in which will definitely not be static and keep changing?

If API is sending request to ServiceNow, they need to whitelist ServiceNow IPs that corresponds to 'The address to which your instance resolves' section.

If ServiceNow is initiating the request to API, use 'Source address used for integrations into customer network with NO VPN' as this is the typical setup used by Customers unless you have setup VPN tunnels.

If ServiceNow is initiating the request to API and you have built VPN tunnels for accessing ServiceNow instance, use 'Source address used for integrations into customer network with VPN'.

not dependent on the location of the user logged into ServiceNow — it's about the network path from the ServiceNow instance to the external API.

-> it's the 1st Option since ServiceNow is consuming the external API and 3rd party team wants to know request is coming from which IP

-> This is the public IP address that your ServiceNow instance uses to make outbound calls without a VPN, which is typically how ServiceNow connects to external APIs unless you've set up a VPN tunnel.

Go to ServiceNow Support Portal -> Automation Store -> My IP Information -> Select the instance and Submit

https://support.servicenow.com/now/en/pages/automation-store?id=ns_automation_store

You can get the Instance IP Address details from section 'The address to which your instance resolves' and can share with the API team for whitelisting.

Thanks Bhuvan. But the section "The address to which your instance resolves" is applicable for inbound calls, right? Not outbound ones?

once you login to now support you can check the links I shared.

that will help you grab the IP and you can share that with the 3rd party to whitelist that.

Yes, that part I understood. But which section to refer to?

"VPN Peer IP Address"
"Source address used for integrations into customer network with NO VPN"
"Source address used for integrations into customer network with VPN"
"The address to which your instance resolves"
