Allowlisting webhook IP addresses for secure server access

{: #webhook-ips}

Learn how to allowlist IP addresses to restrict access to your servers that receive webhooks. For example, you can use our IP addresses to configure your firewall to allow traffic from only these IPs to help make your applications more secure. {: shortdesc}

Outbound webhook notifications come from subnet ranges for specific data center locations and individual IP addresses for multi-zone regions. Review the tables to find the IP addresses by region, and then use them to configure your firewall to allow traffic from only these IPs.
