Freedom Permalinks can help you to change permalinks to any format you want. 
Update slug structure, change domains, remove/add slashes or add extensions (.html, .php or anything you want) etc.
<pre><code>PS. While this gives you freedom to play with permalinks, you should know that you have to make those link structures work with your themes yourself.
</code></pre>
For example if your theme is installed on subdomain1.domain.com, changing permalink to subdomain2.domain.com will break the existing links and you have to move your theme manually to subdomain2.domain.com to make it work.
<pre><code>Things you must know before trying this plugin:
1. It's best suited for custom/smaller themes.
2. Always create backup of your database before trying this plugin.

Examples:
Some permalink examples to just give you some idea to what we can do with "Freedom Permalinks".

WH4U Domains is a WordPress plugin that allows website owners and resellers to offer domain name services directly from their WordPress site. It integrates with the DomainsReseller API to provide real-time domain availability checking, registration, and transfer capabilities.
<h4>Features</h4>
<ul>
<li>Domain Search — Visitors can search for domain availability via a shortcode or Gutenberg block</li>
<li>Public Registration & Transfer — Anonymous visitors can submit domain registration and transfer requests that admins review and approve</li>
<li>Admin Dashboard — Full admin panel for managing orders, viewing API status, and monitoring the retry queue</li>
<li>Reseller Support — Per-user API credentials allow multi-reseller setups</li>
<li>Retry Queue — Failed API calls are automatically retried with exponential backoff</li>
<li>Shopping Cart Redirect — Optional redirect to WHMCS, Blesta, ClientExec, Upmind, or custom cart URL with the domain pre-filled when visitors click Register or Transfer</li>
<li>Internationalization — Fully translatable; Greek translation included</li>
</ul>
<h4>How It Works</h4>
<ol>
<li>Install and activate the plugin</li>
<li>Configure your DomainsReseller API credentials under Domains > Settings</li>
<li>Add the <code>[wh4u_domain_lookup]</code> shortcode or the “Domain Lookup” block to any page</li>
<li>Visitors search for domains — available domains can be registered, and taken domains can be transferred through the frontend form (or, if configured, sent to your WHMCS/Blesta/ClientExec/Upmind cart with the domain in the URL)</li>
<li>Admins review and approve/reject public orders from the WordPress admin</li>
</ol>
<h3>Third-Party Service</h3>
This plugin connects to the DomainsReseller API provided by WebHosting4U to perform all domain-related operations.
<h4>What data is sent</h4>
<ul>
<li>Domain lookups: The domain name being searched is sent to check availability</li>

<li>Domain transfer: Domain name, registration period, and EPP code are sent</li>
<li>TLD and pricing queries: Requests for available TLDs and their pricing are sent</li>
</ul>
<h4>When data is sent</h4>
<ul>
<li>When a visitor performs a domain search on the frontend</li>
<li>When an admin approves a public domain registration order</li>
<li>When an admin submits a registration or transfer order from the admin panel</li>
<li>When TLD lists or pricing are loaded (cached locally for 12 hours)</li>

<h4>Data stored locally</h4>

<ul>
<li>Order records: domain name, registration period, status, and encrypted registrant contact details (encrypted with AES-256-CBC + HMAC at rest)</li>
<li>Public order submissions: stored as a custom post type with encrypted contact data until an administrator approves or rejects them</li>
<li>API logs and notification records: request/response entries and email/webhook dispatch history with secrets redacted. A daily WP-Cron task prunes rows older than 30 days; the retention period is filterable via the <code>wh4u_log_retention_days</code> filter.</li>
<li>Retry queue: failed API calls scheduled for exponential-backoff retry via WP-Cron</li>
<li>Rate-limit counters: short-lived transients keyed by user ID or a salted SHA-256 hash of the visitor IP; used only for abuse protection and expire within minutes</li>
<li>Reseller settings: per-user API credentials, with the API key and optional webhook secret encrypted at rest</li>
</ul>
No data is sent to any third party other than the services listed above.
