## Description
Smooth API Accelerator helps you turn selected WordPress REST API endpoints into
fast, CDN-delivered JSON snapshots.
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.
The plugin is designed for WordPress projects where API performance, stable JSON
delivery, and controlled endpoint syncing matter.
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.
### Why use Smooth API Accelerator?
* ⚡ **Faster WordPress REST API delivery** – serve selected API responses as CDN-
delivered JSON files
* 🌍 **Edge-ready JSON** – make API data available through Smooth CDN for lower
latency
* 🔄 **Automatic updates** – refresh synced endpoints after content and taxonomy
changes
* 📦 **Static JSON snapshots** – predictable, cache-friendly output for frontends
and apps
* 🔒 **Optional protected delivery** – restrict access to selected JSON files when
needed
* 🧠 **Cleaner payloads** – optionally generate structured block data and remove
raw content
* 🧩 **Headless-friendly workflow** – prepare WordPress data for React, Next.js,
mobile apps, and static frontends
Perfect for:
* Headless WordPress websites * Frontends built with React, Next.js,
Astro, Vue, or other frameworks * Mobile apps using WordPress as a backend * Sites
that expose public content through the WordPress REST API * High-traffic REST API
endpoints that benefit from static JSON delivery * Projects that need a controlled
JSON sync workflow instead of custom scripts
### How it works
1. Connect your WordPress site to Smooth CDN using account mode or guest mode
2. Discover available WordPress REST API endpoints
3. Select the endpoints you want to accelerate
4. The plugin generates JSON snapshots for selected endpoints
5. Synced JSON files are uploaded to Smooth CDN
6. Your frontend, app, or external client can use fast CDN URLs instead of generating
the same REST API response on every request
### External services
This plugin connects to Smooth CDN to create and manage the remote project used
for JSON acceleration.
It communicates with Smooth CDN when you:
* start or complete the account or guest connection flow,
* fetch account or project metadata needed by the plugin,
* upload synced JSON snapshots,
* delete synced JSON snapshots with `Unsync` or `Purge endpoints`.
Depending on the action, the plugin may send:
* your site URL and site name,
* the generated project name derived from the site domain,
* authentication data needed to complete the Smooth CDN login flow,
* project identifiers and account metadata required to manage the connection,
* REST API JSON snapshots selected for sync, including paginated collection files,
* asset paths, filenames, and protection flags used to manage synced files.

* Terms of Service: https://smoothcdn.com/terms
* Privacy Policy: https://smoothcdn.com/privacy
### Features
* Simple setup with unified connection and configuration view
* Smooth CDN connection in minutes with account mode or guest mode
* REST API endpoint discovery from wp-admin
* Clear separation between synced and available endpoints
* One-click sync for selected endpoints
* Automatic re-sync after post and taxonomy updates
* Paginated collection sync with metadata manifest
* Optional `blocks` field generation for structured content
* Optional removal of raw `content` field for lighter JSON responses
* Optional protected JSON delivery
* Lock mode for direct REST GET access via `wp-json`
* `Unsync` and `Purge endpoints` remove both local and CDN data
* Clear dashboard with sync and acceleration status
* Developer hooks for custom route refresh rules and payload adjustments
### Synced JSON layout
Single endpoints are uploaded as one JSON file:
```
https://cdn.smoothcdn.com///wp/v2/pages/42.json
```
Collection endpoints are uploaded as:
```
https://cdn.smoothcdn.com///wp/v2/posts.json
https://cdn.smoothcdn.com///wp/v2/posts/page-1.json
https://cdn.smoothcdn.com///wp/v2/posts/page-2.json
```
The collection metadata file contains:
```
{
"per_page": 50,
"total_pages": 2,
"pages": [
"https://cdn.smoothcdn.com///wp/v2/posts/page-1.json",
"https://cdn.smoothcdn.com///wp/v2/posts/page-2.json"
]
}Settings overview
Key settings that affect synced output:
```
* `Add blocks field` adds a normalized `blocks` field when supported content is
available.
* `Remove content field` is available only when `Add blocks field` is enabled and
removes `content` after `blocks` is added.
* `Protected assets` uploads synced JSON files as protected Smooth CDN assets.
* `Collection sync page size` controls pagination for collection endpoints. Available
values: `10`, `25`, `50`, `100`. Default: `50`.
* `Auto scan and sync` controls how often WP-Cron runs automatic scan and sync.
Changing output-affecting settings invalidates previous sync markers and queues
a faster full scan + sync through WP-Cron.
### Developer hooks
Use `scdn_api_accelerator_save_post_related_routes` to add custom routes/templates
that should be refreshed and synced after `save_post`.
Example:
```
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 );
```
Use `scdn_api_accelerator_pre_send_json` to adjust endpoint payload before upload.
Example:
```
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 );Maintenance
`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.License
