Safelist IPs



PagerDuty supports safelisting IP addresses, however, we’d like to highlight that this method of ensuring webhook delivery security is no longer best practice. Over the last year we have added TLS 1.2 and custom headers to our webhooks which will ensure webhooks are delivered from PagerDuty. If you are migrating away from using IP safelisting and have questions about PagerDuty’s webhook deliverability, please contact our Support team.


The EU Service Region

Please make sure to safelist IPs resolving to the URLs corresponding to your service region (currently available regions are US and EU).

Events APIs

PagerDuty’s Events API, which is used for triggering, acknowledging and resolving incidents, requires that your system be able to make outbound connections to on TCP port 443 (for HTTPS). and resolve to multiple IPs, which you can find by querying the A records using dig or nslookup.

Example Query 1 (US)

$ dig a +short

Example Query 1 (EU)

$ dig a +short

In this example, you see that the Events API is accessible in the US region at the IPs, and


To access our REST API, your system must be able to make outbound connections to and/or on TCP port 443. Our REST API only allows HTTPS connections; for security’s sake, HTTP connections are not allowed. and resolve to multiple IPs as well, however these IPs will be different than the ones used for our Events API or webhooks.

Example Query 2 (US)

$ dig a +short

Example Query 2 (EU)

$ dig a +short

Taking the example of the US service region, you see that the REST API is accessible at the IPs, and


The EU Service Region

Customers using REST API-based integrations may need to safelist IPs resolving to both and


Webhooks are HTTP or HTTPS calls sent from PagerDuty to your web server on the IP and port of your choosing. Please see the current list of IPs that PagerDuty uses to send webhooks in our developer documentation, Webhook IPs.

Firewalls and Access Control Lists (ACLs)

You should not expect the IP addresses in the developer documentation Webhook IPs to change, as they are a fixed list of IPs. This means you can safely hardcode them into your firewall or ACL.


Webhook IPs

Prior to May 5th, 2022 the list of Webhooks IPs was subject to change without notice. With that in mind, we provided a couple scripts to notify you and automatically update EC2 security groups when that happened. Since you should not expect Webhook IPs to change, we’ve removed reference to these scripts and they’ve been retired.

Jira Server Integration

If you are using the Jira Server integration, depending on the service region for your account, you will also need to add the address records of or to any sort of safelist that controls network egress traffic; this integration will make API calls to PagerDuty that go directly to the hostname of your account's service region.
