WordPress

With the Beacel plugin

1. In the dashboard open Widget, then Placement, and press Download the Beacel plugin. The file already holds your site's key.
2. In WordPress go to Plugins, then Add New, and press Upload Plugin at the top.
3. Choose the file you downloaded and press Install Now, then Activate Plugin.
4. Back in the dashboard, press Check my site.

You need a WordPress where you can install plugins (your own hosting, or a WordPress.com plan that allows plugins).

Or paste the line yourself

If you would rather not add our plugin, a header and footer plugin can carry the line. With the free WPCode plugin:

1. Copy the code from Widget, then Placement.
2. Install and activate WPCode (Plugins, Add New, search for "WPCode").
3. Open Code Snippets, then its header and footer screen, paste the line into the footer box and save.

<script src="https://beacel.com/widget.js" data-beacel="k9-x_Q2a" async></script>

Chat inside a page, or your own button

The plugin or the footer line already loads the assistant on every page. To show the chat inside one page, edit that page, add a Custom HTML block where the chat should be and paste:

<div data-beacel-inline></div>

To open the chat from a button of your own, put this in a Custom HTML block:

<button type="button" data-beacel-open>Write to us</button>

Check that it works

Open your website once, then press Check my site. Not detected yet. It shows up here a few minutes after your site loads the code. A caching plugin (WP Rocket, LiteSpeed Cache and others) can show visitors an older copy of your pages: if the assistant does not appear, clear its cache.
