When a VIVI agent connects to an external service — such as a CRM, ticketing system, PMS, or custom API — requests leave our platform from a fixed set of outbound IP addresses. If the system you’re integrating with restricts inbound traffic through a firewall, VPN, or access list, you’ll need to add these ranges so VIVI can reach it. Unlike user-facing traffic, which comes from browser or channel endpoints, integration traffic always originates from the ranges listed below.

​
Outbound IP Ranges

Add the following range to your allowlist. Any request sent from a VIVI agent or integration will originate from one of these addresses.

When You Need to Allowlist

You should add VIVI’s outbound IPs if:
  • Your CRM, helpdesk, or internal API restricts access by IP.
  • You’re connecting VIVI to a service behind a corporate firewall or VPN.
  • Your webhook endpoint only accepts traffic from known sources.
If your integration lives on a public platform with no IP restrictions, no action is required.

​
How to Apply the Allowlist

1

Locate your firewall or access settings

This is usually found under Security, Network, or API Access in the destination system’s admin panel.
2

Add VIVI's outbound IP ranges

Enter the CIDR ranges from the table above. Use ranges rather than individual IPs so your integration keeps working as we scale.
3

Test the integration

Trigger the integration from VIVI — for example, run a test conversation or fire a webhook — and confirm the request is accepted.

​
Best Practices

  • Allowlist the full CIDR range, not individual IPs, to avoid breakage when our infrastructure scales.
  • Subscribe to release notes so your network team is notified when ranges change.
  • Re-test your integrations after any firewall or network change on your side.
