3. Requirements

WHMCS 8.9 or newer
PowerDNS 4.x with API enabled

For DNSSEC: gmysql-dnssec=yes in /etc/powerdns/pdns.conf
Valid PowerDNS Manager license

First time using PowerDNS? Follow our server setup guide with DNSSEC configuration before installing this module.

4. PowerDNS Server Configuration

Your PowerDNS configuration file (/etc/powerdns/pdns.conf) needs these settings:

launch=gmysql
gmysql-host=localhost
gmysql-user=pdnsuser
gmysql-dbname=pdnsdb
gmysql-password=your-mysql-password
api=yes
api-key=your-api-key
webserver=yes
webserver-port=8081
webserver-address=0.0.0.0
webserver-allow-from=127.0.0.1,::1,your-whmcs-server-ip,nameserver-ip
master=yes
slave=no
allow-axfr-ips=secondary-server-ip
also-notify=secondary-server-ip
gmysql-dnssec=yes

Important: Include your WHMCS server IP in webserver-allow-from. Without this, you'll get authorization errors.

After making changes, restart PowerDNS:

systemctl restart pdns

5. Installation

Step 1: Upload Files

Upload these folders to your WHMCS installation:

/modules
├─ addons
│   └─ powerdns_manager
└─ servers
    └─ powerdns_manager

Important: Don't rename the folders.

Step 2: Activate the Addon

Go to System Settings → Addon Modules
Find "PowerDNS Manager" and click Activate
Click Configure
Enter your license key and PowerDNS API details:
- PowerDNS API URL: http://your-nameserver.com:8081/api/v1
- API Key: Must match the key in pdns.conf
- Server Name: Usually localhost
- Zone Type: Choose between Native (default) or Master
Configure DNSSEC and other settings
Click Save Changes

Step 3: Set Permissions

Choose which admin groups can use the module.

Step 4: Set Up Server Module (Optional)

To sell DNS hosting as a product:

Go to System Settings → Servers
Add a new server
Choose PowerDNS Manager
Enter the same API details

Step 5: Test API Connection

From your WHMCS server, test the API:

curl -H "X-API-Key: your-api-key" http://your-nameserver.com:8081/api/v1/servers

You should see a JSON response with server information.

How It Works

New domain registered: Creates DNS zone automatically
Zone already exists: Links to existing zone
Domain suspended: Unlinks from WHMCS (zone stays on server)
Domain terminated: Can delete zone (based on your settings)
DNSSEC enabled: Generates keys and provides DS records instantly

Using our PowerDNS setup? The zone monitoring script handles SOA and NS records automatically. Comment out those lines in the fix_zone_records function.

6. Configuration Options

License Key: Your ArkHost license
PowerDNS API URL: Example: http://ns1.example.com:8081/api/v1
API Key: From your PowerDNS pdns.conf file
Server Name: Usually localhost (must match PowerDNS server identifier)
Zone Type: Choose between Native (default) or Master for new zones
Primary/Secondary/Third/Fourth/Fifth NS: Your nameservers (customers can't change the first two)
Default TTL: Time to live for DNS records (in seconds)
Auto-increment SOA Serial: Updates serial number when records change
DNSSEC Support: Enable DNSSEC features for zones
Clear Data on Deactivation: Removes WHMCS data when disabling the module
Show Nameservers in Client Area: Shows NS info to customers
Public DNS Server: DNS server for checking propagation (like 1.1.1.1)
Access Control: Which admin groups can use this module

7. Creating a DNS Hosting Product

Go to Products/Services
Create a new product
Under Module Settings, choose PowerDNS Manager
Save the product

When customers order this product, it creates a DNS zone automatically.

9. Best Practices

Add your WHMCS server IP to PowerDNS whitelist
Use master-slave DNS for redundancy (module only needs to connect to master)
Set TTL between 300-3600 seconds
Back up your PowerDNS database regularly
Test DNSSEC in staging before production
Keep DS records at registrar updated when rotating keys
Use HTTP instead of HTTPS for API URL if SSL isn't properly configured
Configure zone type (Native/Master) based on your setup

See our master-slave guide with DNSSEC for redundant DNS setup.

10. Troubleshooting

Check These First

Module Debug Log: Shows API communication (Setup → Logs)
Activity Log: Shows all PowerDNS Manager actions
Test API access: curl -H "X-API-Key: YOUR_KEY" http://ns1:8081/api/v1/servers
Test zone listing: curl -H "X-API-Key: YOUR_KEY" http://ns1:8081/api/v1/servers/localhost/zones
Test DNSSEC: pdnsutil show-zone example.com
License issues: Check your license and firewall

Common Problems

HTTP 401 or 403 error
Wrong API key or IP not whitelisted in PowerDNS. Check webserver-allow-from includes your WHMCS server IP.
HTTP 404 Not Found
Wrong API URL format or server name. Use exactly: http://your-nameserver.com:8081/api/v1 and server name localhost.
"Nameservers list must be given" error
Your PowerDNS version (4.2 or older) requires different zone creation method. Enable PowerDNS API compatibility mode in module settings.
Zone not created after registration
Check Activity Log for "retry-failed". May need to increase PHP timeout.
Invalid license error
License doesn't match your WHMCS URL. Update it in ArkHost client area.
DNSSEC not working
Check if gmysql-dnssec=yes is set and PowerDNS restarted.
SSL/TLS connection issues
Use HTTP instead of HTTPS if SSL certificates aren't properly configured.
Long DKIM keys truncated
TXT records now support multi-line values properly.
Slow zone listing page
Upgrade to v1.12 - DNSSEC checks now run on-demand instead of blocking page load.

FAQ

Can multiple WHMCS installations use one PowerDNS server?
Yes, but each zone should be managed by only one WHMCS to avoid conflicts.
Does it import existing zones automatically?
Yes. Click "Auto Associate" in admin area to map existing PowerDNS zones to WHMCS domains. After that, it's automatic for new domains.
How do I migrate zones from another DNS server?
Use the zone import feature. Export zones from your old server in BIND format, then import using merge mode to preserve existing records.
Is DNSSEC supported?
Yes, full DNSSEC support with automatic key management. Just click "Enable DNSSEC" and copy the DS records to your registrar.
Why should I use Native vs Master zone type?
Native is recommended for most setups. Master is mainly for traditional AXFR-based replication. Both work with DNSSEC.
Is the module available in my language?
The client area is fully translated in 8 languages: English, Dutch, French, German, Italian, Portuguese (including Brazilian Portuguese), Russian, and Spanish. To add more languages, copy english.php in lang/ folder, rename it (like japanese.php), and translate the text.
