Learn how to configure OpenSRS access for WHMCS with these step-by-step instructions, including links to detailed WHMCS and OpenSRS documentation.

WHMCS supports OpenSRS integration. To enable this, follow these steps:

1. Set up OpenSRS registrar integration in WHMCS if you have not already done so. For instructions, visit [WHMCS OpenSRS Documentation](http://docs.whmcs.com/OpenSRS).
2. Open a support ticket at [Ruachost Hosting Panel](https://dashboard.ruachost.com/) and request that Ruachost unblock the firewall for ports **55000** and **55443** for the IP address range **216.40.33.0/24**.
3. After receiving confirmation that the firewall has been opened, whitelist your server IP address in your OpenSRS account:

   - Log in to your OpenSRS account.
   - Under **Profile Management**, click **Add IPs for Script/API Access**.
   - On the **Script/API Access** page, type the server IP address for your WHMCS installation and click **Add Rule**.

> **Caution:**
It may take up to one hour for the IP whitelist setting to propagate and take effect.

Once completed, WHMCS can access your OpenSRS account.
