Query API

WordPress Playground exposes a simple API that you can use to configure the Playground in the browser.

It works by passing configuration options as query parameters to the Playground URL. For example, to install the pendant theme, you would use the following URL:

You can go ahead and try it out. The Playground will automatically install the theme and log you in as an admin. You may even embed this URL in your website using an <iframe> tag:

<iframe src=""></iframe>

pluginInstalls the specified plugin. Use the plugin name from the plugins directory URL, e.g. for a URL like, the plugin name would be wp-lazy-loading. You can pre-install multiple plugins by saying plugin=coblocks&plugin=wp-lazy-loading&…. Installing a plugin automatically logs the user in as an admin

loginyesLogs the user in as an admin. Set to no to not log in.
multisitenoEnables the WordPress multisite mode.
storageSelects the storage for Playground: none gets erased on page refresh, browser is stored in the browser, and device is stored in the selected directory on a device. The last two protect the user from accidentally losing their work upon page refresh.
import-siteImports site files and database from a zip file specified by URL.
import-wxrImports site content from a WXR file specified by URL. It uses the WordPress Importer, so the default admin user must be logged in.

For example, the following code embeds a Playground with a preinstalled Gutenberg plugin, and opens the post editor:

<iframe src=""> </iframe>
CORS policy

To import files from a URL, such as a site zip package, they must be served with Access-Control-Allow-Origin header set. For reference, see: Cross-Origin Resource Sharing (CORS).
