Contesimal Connector

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 /wp-json/contesimal/v1/ endpoints. The plugin does not send any data externally on its own.

External services and privacy

• Service: Designed to work with Contesimal (https://contesimal.ai), but compatible with any client using your API key.
• Data received: Post title, content (HTML), excerpt, status, categories, tags, post type, author ID, and media URLs with optional title, alt text, caption, and description. User listing and create responses return ID, display name, slug, and roles for active users (no email or passwords in the response). Creating a user accepts username, email, optional password, display name, and an allowlisted role. The administrator role cannot be assigned via the API.
• Media handling: Your WordPress site may download remote files from provided URLs to create Media Library attachments.
• When: Only when a valid API request is sent to your site. No background communication occurs.
• Control: External access is enabled only if you share the API key. You can regenerate the key or deactivate the plugin at any time.
• Consent: By enabling the plugin and sharing the API key, the site administrator allows external applications to submit content and, when used, create users with non-administrator roles.

Authentication

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

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

• API key authentication (hashed storage)
• Create posts via REST API
• List categories, post types, and author-capable users (with roles)
• List assignable roles and create users (allowlisted roles only; never administrator)
• Media import from external URLs
• Rate limiting (per IP)
• Configurable CORS
• Optional request logging (admin only)
• Contesimal admin menu: Connection, Content types, and Field mapping
• Publish config API so Contesimal discovers enabled types and taxonomy maps

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

• GET /ping – Health check
• GET /publish-config – Enabled post types and field (categories/tags) taxonomy maps
• GET /categories – Categories from mapped taxonomies for enabled post types
• GET /post-types – Enabled Contesimal post types (with field maps)
• GET /users – List active users (id, name, slug, roles; optional session_only, search, limit)
• POST /users – Create a user with an allowlisted role
• GET /roles – List roles that may be assigned via POST /users
• GET /posts – List posts by enabled post type with pagination and total count
• POST /publish – Create post (uses Field mapping for categories/tags)
• POST /media/import – Import media from URLs (optional title, alt, caption, description)

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

REST API Reference

All endpoints require: X-API-Key: your_api_key

GET /wp-json/contesimal/v1/ping

Returns plugin status.

Response:
{ “status”: “ok”, “plugin”: “contesimal-connector”, “version”: “1.0.8” }

GET /wp-json/contesimal/v1/publish-config

Returns the site’s Contesimal publish map: default post type and each enabled type with whether categories/tags are mapped and to which taxonomies.

Response (example):
{ “success”: true, “default_post_type”: “post”, “post_types”: [ { “name”: “post”, “label”: “Posts”, “is_default”: true, “fields”: { “title”: true, “content”: true, “excerpt”: true, “author”: true, “featured_image”: true, “categories”: { “enabled”: true, “taxonomy”: “category” }, “tags”: { “enabled”: true, “taxonomy”: “post_tag” } } } ] }

GET /wp-json/contesimal/v1/categories

Returns active terms from taxonomies mapped as Contesimal “categories” for enabled post types. Each item includes taxonomy and post_types (enabled types that use that taxonomy for categories).

Response (example):
{ “success”: true, “categories”: [ { “id”: 1, “name”: “Uncategorized”, “slug”: “uncategorized”, “count”: 5, “taxonomy”: “category”, “post_types”: [ “post” ] } ] }

GET /wp-json/contesimal/v1/post-types

Returns post types enabled under Contesimal → Content types, plus default_post_type and per-type fields (categories_taxonomy / tags_taxonomy).

GET /wp-json/contesimal/v1/users

Returns active (non-deleted / non-spam) users. Suitable for user management UI and for author_id on POST /publish. Never returns email or passwords.

Query parameters (all optional):

Parameter
Description

search
Substring match on login, nicename, display name, or email

session_only
1 to only include users with stored WordPress session tokens (typically logged in recently)

limit

Response (example):
{ “success”: true, “users”: [ { “id”: 1, “name”: “admin”, “slug”: “admin”, “roles”: [ “administrator” ] } ] }

GET /wp-json/contesimal/v1/roles

Returns roles that may be assigned when creating a user. Privileged roles (e.g. administrator) are never included.

Response (example):
{ “success”: true, “roles”: [ { “slug”: “author”, “name”: “Author” }, { “slug”: “editor”, “name”: “Editor” } ] }

Default allowlist: subscriber, contributor, author, editor. Roles that exist on the site and do not grant dangerous capabilities (such as manage_options or edit_users) are returned.

POST /wp-json/contesimal/v1/users

Creates a WordPress user. Not supported on multisite. The administrator role cannot be assigned.
