Calendly IP address update

In our ongoing efforts to enhance the security and reliability of our software, we will be updating the public IP addresses used by our website and APIs. The change to the IP addresses is scheduled for January 16, 2024

If your company policy requires you to allowlist Calendly IP Addresses for your inbound integrations (e.g., through a firewall or similar security device) then please take the following action to ensure uninterrupted service:

Allowlist New IP Addresses

Update your firewall or security settings to automate the inclusion of the new IP addresses. The updated list IP addresses can be found at this developer endpoint.  Please review the list and update your firewall settings where necessary to avoid any disruptions to your integrations with Calendly.

Recommended Action

After completing the IP address update, we recommend testing your usage of Calendly to confirm that service remains unaffected.
