Jetpack for developers

If you’re a developer, Jetpack includes tools to extend and customize Jetpack to fit your needs.

For the most complete and up-to-date developer documentation — including REST APIs,

The sections below cover common developer tasks for theme and plugin authors using
the Jetpack plugin.

Work in your local environment with JetpackMD

When working on a theme or a plugin in your local environment, you can enable the Jetpack Development mode to use features that do not require a connection to the WordPress.com servers.

To use Jetpack in Development mode, you can add the following code to your wp-config.php file:

define( 'JETPACK_DEV_DEBUG', true );
