Playground APIs Concepts

WordPress Playground in the browser is all about links and iframes. Regardless of which API you choose, you will use it in one of the following ways:

You can customize WordPress Playground by modifying the link. You can, for example, create a post, request a specific plugin, or run any PHP code.

To prepare such a link, use either the Query API (easy) or the JSON Blueprints API (medium).

Once it's ready, simply post it on your site. It makes a great "Try it yourself" button in a tutorial, for example.

Embed in an <iframe>

WordPress Playground can be embedded in your app using an <iframe>:

<iframe src=""></iframe>

To customize that Playground instance, you can:

The JavaScript API gives you the most control, but it is also the least convenient option as it requires loading the Playground Client library.

If you need certain availability, you should host your own WordPress Playground.

These APIs are very similar to their web counterparts, but, unsurprisingly, they are not based or links or iframes.
