Official Intercom support for WordPress
Please note that this plugin is in Beta.
With the Intercom plugin for Wordpress, you can chat to both logged-in and anonymous users (using Acquire).
Installing this plugin provides a new Intercom settings page, which allows you to configure your app id and secure mode secret. Once filled out, the Intercom widget will automatically appear.
$current_user is present, their email will be used as an identifier in the widget. Otherwise, it falls back to anonymous chat using Acquire.
