Install the official Usero plugin, or paste one script in the footer.
There is an official Usero plugin in the wordpress.org directory, so for most sites the cleanest path is to search for it under Plugins, activate, and enter your client id. If you would rather not add a plugin, the vanilla script in your footer works on any theme.
<!-- in your theme's footer.php, just before </body> -->
<script src='https://unpkg.com/@usero/sdk'></script>
<script>
Usero.initUseroFeedbackWidget({ clientId: 'YOUR_CLIENT_ID' })
</script># Plugins > Add New > search "Usero"
# Activate, then paste your client id in the settings field.
# The plugin vendors the SDK, so no external script tag is loaded.Replace YOUR_CLIENT_ID with the id from your Usero dashboard.
Built for WordPress
Usero ships a plugin to the WordPress directory. Install it, enter your client id, done. It vendors the SDK locally instead of loading from a CDN.
Block themes, classic themes, page builders. The footer script works the same everywhere a theme lets you add markup before the closing body tag.
The script is a static tag, so WP Super Cache, W3 Total Cache, and LiteSpeed cache it like any other markup. No PHP runs per request.
WordPress has no bundler in the typical install. The script tag needs none, which is exactly why it suits the platform.
Canny still needs an account dance and a 200kb iframe even on WordPress. Usero is a directory plugin or a single 12kb script.
