Hey guys, can you please help me out with the following request? we received a call from IDCM on behalf of Island Dental Associates, him was trying to whitelist a domain to be able to use an API to communicate and pull data from the software (opendental), therefore he was trying to whitelist the following domain api.opendental.com, I was able to access to the access to the whatguard settings to try to add the policy, but I am not totally sure about what should be the best process of doing this, checked on the following link; https://www.watchguard.com/help/docs/help-center/en-us/Content/en-US/Fireware/policies/fqdn_about_c.html#DNS

# Whitelist domain for OpenDental API communication through WatchGuard firewall

## Problem
A client office needed to whitelist the domain `api.opendental.com` in their WatchGuard firewall to allow OpenDental software to communicate with its API and pull data. The technician had access to the WatchGuard settings but was unsure of the correct process for adding the domain whitelist policy.

## Resolution
Follow the established procedure for adding WebBlocker exceptions in WatchGuard Fireware:

1. Access the WatchGuard Fireware Web UI
2. Navigate to Firewall > Aliases section
3. Use the documented procedure for adding WebBlocker exceptions to whitelist the required domain
4. Add `api.opendental.com` as an exception to allow API communication

Refer to the internal documentation for detailed step-by-step instructions on configuring WebBlocker exceptions in WatchGuard firewalls.
