When Jetpack is activated on your self-hosted site and connected to WordPress.com, you can then use the WordPress.com REST API console to do cool stuff like edit a post, reblog a post, return the Media Library, create a new category, get a list of your Jetpack connected blogs, and more.
You can even migrate followers from a WordPress.com blog to a Jetpack-enabled blog!
Using the console can help you understand the power of the API and how your site(s)’ data is structured without looking into the database.
Just go to WordPress.com and login as the user that is connected to the site(s) you want to use the console with.
If you aren’t logged in to WordPress.com, the console won’t look any different, but it will give you authentication error messages when you try to do stuff.
After logged in, visit the console link (beginning of this post) and get started.
Tip: When first getting started, just try the “GET” commands because the “POST” commands actually change stuff.
For example, if you click on the Reference to “Disconnect a Jetpack-enabled blog from a WordPress.com user,” know that it will actually de-register your site from its WordPress.com connection (then you’d need to login to your site’s Dashboard and re-connect Jetpack to WordPress.com).
