WordPress chatbot: add Kyros to your WordPress site

1. Copy the snippet in Kyros

1. Open your assistant and go to “Deploy”.
2. Click “Install the widget” and choose “Floating bubble” (a chat button in the corner of every page) or “Inline frame” (embedded in the page content).
3. Pick the “WordPress” tab and copy the code. Under “Advanced” → “Code expiry” you decide whether the signed code expires after 7, 30 or 90 days, after a year, or never.
4. In the widget settings, add your WordPress domain under “Website access”; wildcards cover subdomains. That sets which domains the chat can open on. On other domains the chat button still shows, but the chat window won’t load. With no entry, the chat appears on any website.

2. On one page: the Custom HTML block

For the inline frame, or for the bubble on a single page only:

1. Open the page in the block editor.
2. Add the Custom HTML block with the block inserter or by typing /html.
3. Choose “Edit HTML”, paste the code, then click “Update”.

The block keeps <script> and <iframe> only for users with the unfiltered_html capability. On a single site, the Administrator and Editor roles have it; on Multisite, only Super Admins do. For everyone else, WordPress strips these tags from the block.

3. On every page: code before </body>

For the floating bubble on every page, you have three routes:

• A plugin for header and footer code. Without touching theme files, add the snippet to the footer with a third-party plugin, for example “WPCode – Insert Headers and Footers + Custom Code Snippets” from the WordPress plugin directory. The plugin isn’t made by Kyros; its documentation describes the menus.
• Classic theme: footer.php in a child theme. Open Appearance → Theme File Editor and paste the code into your child theme’s footer.php, right before </body>. Don’t edit the theme itself: according to the WordPress docs, those changes are overwritten by the next theme update, while a child theme keeps yours.
• For developers: wp_enqueue_script(). In your child theme, load the script on the wp_enqueue_scripts hook with the in_footer and 'strategy' => 'defer' arguments (array form since WordPress 6.3).

Classic theme or block theme?

With a classic theme, the Theme File Editor sits under Appearance; with a block theme, it sits under Tools. Block themes build the footer as a template part that you edit in the Editor (Appearance → Editor → Patterns → Template Parts). The footer.php route is therefore meant for classic themes; with a block theme, use the plugin or wp_enqueue_script(). If the file editor is missing entirely, it may be switched off with DISALLOW_FILE_EDIT in wp-config.php.

A note on WordPress.com

On WordPress.com, you can add tags such as script and iframe only on a paid plan with hosting features activated. They are activated as soon as you install at least one plugin. Sources differ on which plans can install plugins: the current support page lists all paid plans (Personal, Premium, Business and Commerce), while a blog post from August 2025 called plugin access on Personal and Premium a limited-time offer. Check your plan on the plugins support page (as of October 1, 2026).
