Auto Poster - REST Publishing Bridge is a small, free, GPL-licensed plugin that gives authorized external applications — JacAI SMM, JacAI Writer, or anything else you run — a protected REST endpoint to create, update, schedule, and publish posts. It ships no AI service and no external account; it's purely the bridge.
Every request is authenticated — nothing publishes to your site unless it carries your key.
A random key generated inside WordPress, sent via the X-AutoPoster-Key request header.
Re-sending the same external article_id updates the existing post instead of creating a duplicate — safe against retries.
Posts can land as drafts, publish immediately, or land as scheduled posts, with configurable author and default category.
Sideloads featured images with WordPress safe-URL checks, file-size limits, and image-type validation (JPEG, PNG, GIF, WebP, AVIF, 12 MB default cap).
Optional Yoast SEO / Rank Math metadata compatibility, plus optional Polylang language metadata.
An optional HMAC-signed webhook fires after publication, so your other systems can react without polling.
JacAI SMM and JacAI Writer both publish to WordPress through this exact plugin — install it once, and every JacAI product that generates content can reach your site.
Auto Poster is free and already WordPress.org-listing-ready. Install it, copy your key into JacAI SMM or JacAI Writer, and you're connected.
Upload the plugin folder to /wp-content/plugins/ or install through Plugins → Add New → Upload Plugin, activate, then open Settings → Auto Poster to copy your endpoint and key.
Auto Poster is the publishing half — JacAI generates the content that flows through it.
