Manual Integration (Alternative Method)

If you need custom integration, here's how to add a Mailchimp subscribe form to checkout:

Add this code to your theme's functions.php:

add_action('woocommerce_after_checkout_billing_form', 'add_mailchimp_checkbox');
function add_mailchimp_checkbox($checkout) {
    woocommerce_form_field('mailchimp_signup', array(
        'type' => 'checkbox',
        'class' => array('input-checkbox'),
        'label' => __('Subscribe to our newsletter'),
        'default' => 1
    ));
}

Process the subscription when order is placed:

add_action('woocommerce_checkout_update_order_meta', 'process_mailchimp_signup');
function process_mailchimp_signup($order_id) {
    if ($_POST['mailchimp_signup']) {
        $order = wc_get_order($order_id);
        $email = $order->get_billing_email();
        
        // Add your Mailchimp API call here
        // Use Mailchimp API v3
    }
}
