If you are seeking information about the static IPs we use for APIs and webhooks, this guide has been created to clarify your doubts and help you maintain a secure connection with our services!

What Are Static IPs?

Static IPs are Internet addresses that do not change over time. They are essential to ensure constant and reliable communication between systems, such as the interaction between your network and ZapSign.

ZapSign's Static IPs:

Here are the static IPs we use; take note:
44.215.73.113
44.196.128.113
44.221.99.222
54.82.108.236
54.80.207.131
52.223.0.32
35.71.128.12
52.71.5.23

Importance of Configuring Your Firewall:

Configuring your firewall to recognize and allow these static IPs is crucial. This prevents unwanted blocks and ensures that communications between your system and ZapSign flow without interruptions.

Understanding and correctly using ZapSign's static IPs along with the proper configuration of your firewall are key to a smooth and secure user experience. This helps avoid connectivity issues and keeps your electronic signature operations running smoothly.
