I found this useful from the woocommerce developer documentation.

You can simply call is_woocommerce_active() function within your plugin file.

Example if ( ! is_woocommerce_active() ) { add_action( 'admin_notices', 'WC_Subscriptions::woocommerce_inactive_notice' ); return; }

is_woocommerce_active defined as below as per woo documentation `` /**

• Check if WooCommerce is activated */ if ( ! function_exists( 'is_woocommerce_activated' ) ) { function is_woocommerce_activated() { if ( class_exists( 'woocommerce' ) ) { return true; } else { return false; } } } ``
