WPES-Envato-Theme-Update

Make your Buyers happy with Automatic update your theme through Envato APIs class, made for Theme Authors on Envato Marketplace.

Installing:

Step 1: Moves wpes-envato-theme-update.php to your theme inc directory.
Step 2: Put this at the end of your functions.php file

if( ! function_exists( 'update_my_theme' ) ){
	function update_my_theme() {
		if( class_exists( 'WPES_Envato_Theme_Update' ) ){
			new WPES_Envato_Theme_Update( basename( get_template_directory() ) , 'Purchase code' , 'Buyer personal access token' , false );
		}
	}
	add_action( 'init' , 'update_my_theme' );
}

So the code will be looks like this.

require get_template_directory() . '/inc/wpes-envato-theme-update.php';
if( ! function_exists( 'update_my_theme' ) ){
	function update_my_theme() {
		if( class_exists( 'WPES_Envato_Theme_Update' ) ){
			new WPES_Envato_Theme_Update( basename( get_template_directory() ) , 'Purchase code' , 'Buyer personal access token' , false );
		}
	}
	add_action( 'init' , 'update_my_theme' );
}

As theme author, I believe that you know how to pass the purchase code and buyer personal token key values through the Theme Options.
