Whether you are enforcing strict Firewall policies, connecting with API, or securing your voice flow, understanding SnapCall's IP address whitelisting scenarios is essential.

Here is a roundup of the IP address details from across our platform.

REST API

The REST API's IP addresses are highly dynamic across a vast range, so it's not practical to whitelist based on IP addresses. Instead, we recommend you allow all outbound HTTPS traffic to any *.snapcall.io subdomain.

SnapCall Client & SDKs

The original SnapCall web client and also SDKs allow you to connect directly to SnapCall from a web browser or a custom mobile application.

Here are the network requirements for SnapCall web client and SDK connections:
