<p>Smooth API Accelerator helps you turn selected WordPress REST API endpoints into fast, CDN-delivered JSON snapshots.</p>
<p>Instead of generating the same REST API responses on every request, the plugin lets you select endpoints, build static JSON snapshots, and sync them to Smooth CDN. Your frontend, mobile app, headless site, or external client can then fetch predictable JSON files from CDN URLs with low latency and better cache behavior.</p>
<p>The plugin is designed for WordPress projects where API performance, stable JSON delivery, and controlled endpoint syncing matter.</p>
<p>Use it for headless WordPress sites, React or Next.js frontends, mobile apps, public API-like content feeds, and high-traffic REST API responses that do not need to be generated dynamically on every request.</p>
<h3>Why use Smooth API Accelerator?</h3>
<ul>
<li>⚡ <strong>Faster WordPress REST API delivery</strong> – serve selected API responses as CDN-delivered JSON files</li>
<li>🌍 <strong>Edge-ready JSON</strong> – make API data available through Smooth CDN for lower latency</li>
<li>🔄 <strong>Automatic updates</strong> – refresh synced endpoints after content and taxonomy changes</li>
<li>📦 <strong>Static JSON snapshots</strong> – predictable, cache-friendly output for frontends and apps</li>
<li>🔒 <strong>Optional protected delivery</strong> – restrict access to selected JSON files when needed</li>
<li>🧠 <strong>Cleaner payloads</strong> – optionally generate structured block data and remove raw content</li>
<li>🧩 <strong>Headless-friendly workflow</strong> – prepare WordPress data for React, Next.js, mobile apps, and static frontends</li>
</ul>
<p>Perfect for:<br />
* Headless WordPress websites<br />
* Frontends built with React, Next.js, Astro, Vue, or other frameworks<br />
* Mobile apps using WordPress as a backend<br />
* Sites that expose public content through the WordPress REST API<br />
* High-traffic REST API endpoints that benefit from static JSON delivery<br />
* Projects that need a controlled JSON sync workflow instead of custom scripts</p>
<h3>How it works</h3>
<ol>
<li>Connect your WordPress site to Smooth CDN using account mode or guest mode</li>
<li>Discover available WordPress REST API endpoints</li>
<li>Select the endpoints you want to accelerate</li>
<li>The plugin generates JSON snapshots for selected endpoints</li>
<li>Synced JSON files are uploaded to Smooth CDN</li>
<li>Your frontend, app, or external client can use fast CDN URLs instead of generating the same REST API response on every request</li>
</ol>
<h3>External services</h3>
<p>This plugin connects to Smooth CDN to create and manage the remote project used for JSON acceleration.</p>
<p>It communicates with Smooth CDN when you:</p>
<ul>
<li>start or complete the account or guest connection flow,</li>
<li>fetch account or project metadata needed by the plugin,</li>
<li>upload synced JSON snapshots,</li>
<li>delete synced JSON snapshots with <code>Unsync</code> or <code>Purge endpoints</code>.</li>
</ul>
<p>Depending on the action, the plugin may send:</p>
<ul>
<li>your site URL and site name,</li>
<li>the generated project name derived from the site domain,</li>
<li>authentication data needed to complete the Smooth CDN login flow,</li>
<li>project identifiers and account metadata required to manage the connection,</li>
<li>REST API JSON snapshots selected for sync, including paginated collection files,</li>
<li>asset paths, filenames, and protection flags used to manage synced files.</li>

<h3>Synced JSON layout</h3>
<p>Single endpoints are uploaded as one JSON file:</p>
<pre><code>https://cdn.smoothcdn.com/<user-slug>/<project-slug>/wp/v2/pages/42.json
</code></pre>
<p>Collection endpoints are uploaded as:</p>
<pre><code>https://cdn.smoothcdn.com/<user-slug>/<project-slug>/wp/v2/posts.json
https://cdn.smoothcdn.com/<user-slug>/<project-slug>/wp/v2/posts/page-1.json
https://cdn.smoothcdn.com/<user-slug>/<project-slug>/wp/v2/posts/page-2.json
</code></pre>
<p>The collection metadata file contains:</p>
<pre><code>{
    "per_page": 50,
    "total_pages": 2,
    "pages": [
        "https://cdn.smoothcdn.com/<user-slug>/<project-slug>/wp/v2/posts/page-1.json",
        "https://cdn.smoothcdn.com/<user-slug>/<project-slug>/wp/v2/posts/page-2.json"
    ]
}<h3>Settings overview</h3>Key settings that affect synced output:
</code></pre>
<ul>
<li><code>Add blocks field</code> adds a normalized <code>blocks</code> field when supported content is available.</li>
<li><code>Remove content field</code> is available only when <code>Add blocks field</code> is enabled and removes <code>content</code> after <code>blocks</code> is added.</li>
<li><code>Protected assets</code> uploads synced JSON files as protected Smooth CDN assets.</li>
<li><code>Collection sync page size</code> controls pagination for collection endpoints. Available values: <code>10</code>, <code>25</code>, <code>50</code>, <code>100</code>. Default: <code>50</code>.</li>
<li><code>Auto scan and sync</code> controls how often WP-Cron runs automatic scan and sync.</li>
</ul>
<p>Changing output-affecting settings invalidates previous sync markers and queues a faster full scan + sync through WP-Cron.</p>
<h3>Developer hooks</h3>
<p>Use <code>scdn_api_accelerator_save_post_related_routes</code> to add custom routes/templates that should be refreshed and synced after <code>save_post</code>.</p>
<p>Example:</p>
<pre><code>add_filter( 'scdn_api_accelerator_save_post_related_routes', function( $rules, $post_id, $post ) {
    $rules[] = 'product|route:/custom/v1/products/{post_id}';
    $rules[] = 'product|template:/custom/v1/products';
    $rules[] = [
        'post_type' => 'page',
        'route'     => '/custom/v1/page-index',
    ];

    return $rules;
}, 10, 3 );
</code></pre>
<p>Use <code>scdn_api_accelerator_pre_send_json</code> to adjust endpoint payload before upload.</p>
<p>Example:</p>
<pre><code>add_filter( 'scdn_api_accelerator_pre_send_json', function( $data, $route, $context ) {
    if ( '/wp/v2/posts' === $route && is_array( $data ) ) {
        foreach ( $data as $index => $item ) {
            if ( ! is_array( $item ) ) {
                continue;
            }

            unset( $data[ $index ]['class_list'], $data[ $index ]['meta'] );
        }
    }

    return $data;
}, 10, 3 );<h3>Maintenance</h3>`Unsync` removes selected endpoints from sync, deletes their CDN files, and returns them to detected state.

Purge endpoints removes all synced data from Smooth CDN and clears local state.<h3>License</h3>GPLv2 or later

Smooth API Accelerator

Pre-build WordPress REST API responses and serve them as fast JSON snapshots from Smooth CDN.

<p>The simplest method to link WordPress with external APIs</p>
<p>JCI simplifies the task of retrieving data from a third-party REST API. The returned JSON-, XML, CSV, TXT-data can be neatly arranged and showcased on your WordPress site via a shortcode, a JCI Block or PHP. The plugin can generate a template for the data display.</p>
<p>20 seconds: Load API and display data</p>

<h3>Main Plugin Features</h3>
<ul>
<li>Low code usage: Save time and avoid coding using an API</li>
<li>Insert an API-URL into Step 1: Data is loaded, and and displayed. Save it as API-Access-Set.</li>
<li>Use the API-Access-Set in Step 2 to create a Shortcode</li>
<li>Optional for maximum flexibility: Use the API-Access-Set n PHP code</li>
<li>Insert an API-URL into the JCI Block: Data is loaded, and a template can be generated to display the data.</li>
<li>Easy to start: Check Installation – Is your WordPress ready for JCI? Most probably!</li>
<li>Basic Settings: Check SSL, Cacher, Gutenberg and Authentication</li>
<li>ContactForm7 Integration: Populate CF7 forms with JSON data and forward CF7-submitted data to an API.</li>
<li>Use the JCI cacher to avoid many API requests</li>
<li>JCI-Block :  Use the simple JCI Block interface to get data! Query the API and check the response. Then utilize the simple template generator inside the JCI Block to use the data!</li>
<li>Contact Form 7 Integration: Fill form and submit to API</li>
</ul>
<h3>Important Note Starting with Version 2.0.11</h3>
<p>Starting with version 2.0.11, any HTML code present in the shortcode or block is filtered to prevent dangerous code (e.g. JavaScript) from being output.<br />
However, if you want to allow certain tags or attributes as a deliberate choice:<br />
In the plugin’s “Basic Settings” there is a field called “Allow additional HTML tags (advanced)”.<br />
There you can enter comma-separated tags that should not be filtered out. For example, “iframe,script” would preserve these two tags in the HTML output.<br />
“tr#onclick” would preserve the “onclick” attribute in ”, which would otherwise be removed.</p>

Get Use APIs – JSON Content Importer


All I wanted to do is display the latest version number of my own plugin on my site.  I could have spent hours coding it myself, instead I spent 5 minutes installing and working out this plugin.  Great work Bernhard


Easy Peasy


learning curve is very steep with the plugin but it simply works and i fell in love with it! i use it for everything: fetching flight prices, weather data, syncing wordpress blocks / content across different sites / domain through wp rest api to name a few!


such a clever plugin

Connects an API to WordPress: Get API-data (JSON, XML, CSV...), show it with a Shortcode, a JCI Block or PHP. Generate a template with the JCI Block
