# Webhook IP addresses

> IP addresses used by incident.io webhooks

If you need to allowlist IPs for incoming webhooks from incident.io, here are the addresses to add. Our webhooks are powered by [Svix](https://svix.com/), hosted in the EU region.

```plaintext theme={null}
52.215.16.239
54.216.8.72
63.33.109.123
```

To keep a firewall rule up to date automatically, fetch these from
[`GET /v1/ip_ranges`](https://docs.incident.io/api-reference/utilities-v1/list-ip-ranges)
instead of copying them from this page. The endpoint needs no API key, and returns these
alongside the addresses our integrations and workflow webhook steps use.

Because Svix operate these addresses rather than us, we cannot promise notice before they
change. Svix publish their own list at
[docs.svix.com/webhook-ips.json](https://docs.svix.com/webhook-ips.json).
