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

[Nisar3]

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'.

If this helped to answer your query, please mark it helpful & accept the solution.

Thanks,

Interesting, I didn't know that. But I'm unsure how to select multiple. It only shows me one option to select as "Accept as Solution"
