# Webhook IP addresses

> Allowlist Tesouro webhook IP addresses to ensure your endpoints accept incoming webhook notifications.

Tesouro sends [webhooks](/finops/guides/getting-started/webhooks/index) from the IP addresses listed below.
If your network settings restrict access for inbound connections, you can add these IP addresses to your firewall's allowlist.

Different Tesouro [environments](/finops/api/concepts/environments) use different IP addresses.
