Composer — pick a Page, write a message, attach an image, choose post type, send or schedule.
One Two Three Post is a WordPress plugin for site owners who manage one or more Facebook Pages and want a clean composer + scheduler inside WordPress instead of switching to Meta’s tools.
The plugin is fully functional on its own. A separate companion plugin (One Two Three Post Pro, distributed independently) will add AI-generated post drafting and Publer-style multi-network support — One Two Three Post does not require it.
This plugin contacts the following Facebook endpoints using credentials you provide. Nothing is sent to any third party without you connecting first.
https://www.facebook.com/v19.0/dialog/oauth) — the OAuth dialog the user is redirected to when clicking “Connect to Facebook” in Settings. Standard Facebook Login flow.https://graph.facebook.com/v19.0) — for the OAuth code-to-token exchange, listing the user’s Pages, fetching Page metadata, publishing posts and comments, scheduling posts. Called only after the user has connected a Page and only when posting / scheduling.The plugin itself does not phone home to any other server. No analytics, no telemetry, no third-party trackers, no opt-in newsletter signups, no remote update channel.
The plugin requests three Facebook scopes during the Connect flow:
