🔐 Security Update: API IP Address Whitelisting is Now Live
At ZPayNG, security remains one of our highest priorities.
As part of our continued efforts to protect the ZPayNG platform from unauthorized access, we have introduced API IP Address Whitelisting for all API integrations.
What does this mean for you?
If you're using any of the following:
• ZPayNG WHMCS Module
• ZPayNG WooCommerce Plugin
• ZPayNG WordPress Plugin
Or you've integrated the ZPayNG API into your website or application
you must whitelist your server's public IP address from your ZPayNG Profile Settings before your application can access our API.
If your IP address has not been whitelisted, you will receive the following response:
> Access denied. Your IP address ({$requestIp}) is not whitelisted. Please add it to your API IP whitelist in your profile settings.
✅ What you need to do
1. Log in to your ZPayNG account.
2. Go to Profile Settings.
3. Open API IP Whitelist.
4. Add your server's public IP address.
5. Save your changes.
Once your IP has been added, your API requests will continue to work normally.
This enhancement helps safeguard your integrations by ensuring that only authorized servers can communicate with the ZPayNG API.
Thank you for choosing ZPayNG.
