Plugchat lets you add a Meta (Facebook) Messenger chat widget to your WordPress site so visitors can message you directly.
Version 3.0 — Rebuilt for Meta’s New Chat Plugin
Meta has retired the old Customer Chat Plugin SDK. Plugchat 3.0 is rebuilt around Meta’s current system: you copy the embed code from Meta Business Suite and paste it into the plugin settings. That’s it — no API keys, no app IDs, no SDK configuration.
<h4>How it works</h4>
<ol>
<li>Get your Chat Plugin code from Meta Business Suite.</li>
<li>Paste it into Plugchat settings.</li>
<li>Choose left or right position.</li>
<li>Save. Your Messenger chat widget is live.</li>
</ol>
<h4>Features</h4>
<ul>
<li>Simple embed code setup — paste and save.</li>
<li>Position control — left or right side of the screen.</li>
<li>Zero external scripts loaded by the plugin — Meta’s embed code handles everything.</li>
<li>Fully compatible with WordPress 6.9.</li>
<li>Clean uninstall — all settings removed when you delete the plugin.</li>
<li>Existing users with legacy settings are not affected — old configuration is preserved and accessible.</li>
</ul>
<h4>Important Note</h4>
Meta (Facebook) deprecated the legacy Customer Chat Plugin SDK. The old method (entering a Page ID) no longer works for new setups because Meta shut down the SDK endpoint. This is a Meta platform decision and is outside this plugin’s control.
Plugchat 3.0 solves this by using Meta’s current embed code system. If you were using the old version, your settings are preserved and you can reference them while migrating.
