Contesimal

wondermentapps

Contesimal Connector adds REST API endpoints to your WordPress site, allowing external applications to create and manage content using an API key.

Requests are made to your site’s <code>/wp-json/contesimal/v1/</code> endpoints. The plugin does not send any data externally on its own.

External services and privacy

<ul>
<li>Service: Designed to work with Contesimal (https://contesimal.ai), but compatible with any client using your API key.</li>
<li>Data received: Post title, content (HTML), excerpt, status, categories, tags, post type, author ID, and media URLs. The optional users endpoint returns public-style author fields (ID, display name, slug) for users who can edit posts—no passwords or email.</li>
<li>Media handling: Your WordPress site may download remote files from provided URLs to create Media Library attachments.</li>
<li>When: Only when a valid API request is sent to your site. No background communication occurs.</li>
<li>Control: External access is enabled only if you share the API key. You can regenerate the key or deactivate the plugin at any time.</li>
<li>Consent: By enabling the plugin and sharing the API key, the site administrator allows external applications to submit content.</li>
</ul>

Authentication

All endpoints require an API key sent in the <code>X-API-Key</code> header (or <code>Authorization: Bearer</code>).

The key is:
– Generated on your site
– Stored as a secure hash
– Managed by administrators only

Requests without a valid key are rejected (401). Rate limiting is applied per IP.

API keys should be treated as sensitive credentials and only shared with trusted systems.

Features

<ul>
<li>API key authentication (hashed storage)</li>
<li>Create posts via REST API</li>
<li>List categories, post types, and author-capable users (IDs for <code>author_id</code>)</li>
<li>Media import from external URLs</li>
<li>Rate limiting (per IP)</li>
<li>Configurable CORS</li>
<li>Optional request logging (admin only)</li>
</ul>

REST endpoints (base: <code>/wp-json/contesimal/v1</code>)

<ul>
<li><code>GET /ping</code> – Health check</li>
<li><code>GET /categories</code> – List categories</li>
<li><code>GET /post-types</code> – List public post types</li>
<li><code>GET /users</code> – List users with <code>edit_posts</code> (optional <code>session_only</code>, <code>search</code>, <code>limit</code>)</li>
<li><code>GET /posts</code> – List posts by post type with pagination and total count</li>
<li><code>POST /publish</code> – Create post</li>
<li><code>POST /media/import</code> – Import media from URLs</li>
</ul>

An admin notice is shown when API access is enabled, indicating that external publishing is active.

This plugin allow to build relation between 2 custom types (posts, page, custom), very useful for manage related content on CMS type website.
A few example use cases:
<ul>
<li>manually lists of related posts</li>
<li>post series</li>
<li>rented houses connected to agency</li>
<li>etc.</li>
</ul>
Relationships are created from a settings page from the administration console.
This plugin can not do relationships with users, you should test this excellent plugin made by scribu
