The following is a list of IP addresses that you will need to allow traffic from Build Integrations into your system. It is highly recommended that you have additional security in place besides allowing specific IP addresses as IP addresses can be spoofed.
NOTE: More information on proxy settings related to integrations can be found in the Proxy Request section of the How to Create an API Integration article. By default integrations do not use these fixed IPs unless the Proxy Request is enabled.
NOTE: This IP address is specific to our mail server; since we can't guarantee all emails will route through this specific IP we recommend following the DMARC protocol to verifying emails rather than doing an IP allow list).
*Please note all IP addresses are subject to change*
