Add reCaptcha v2 to WooCommerce Checkout
* Add reCaptcha to checkout form
* Note: Can't place within the payment part of the form, WooCommerce just won't show it, choose an appropriate action to add it to accordingly
* @param $checkout
function doublee_show_me_the_checkout_captcha($checkout) {
echo '<div class="g-recaptcha" data-sitekey="YOUR_KEY_HERE"></div>';
add_action('woocommerce_checkout_order_review', 'doublee_show_me_the_checkout_captcha', 18);
* Validate reCaptcha
function doublee_process_recaptcha() {
$postdata = $_POST['g-recaptcha-response'];
$verified_recaptcha = file_get_contents(''.$postdata);
$response = json_decode($verified_recaptcha);
if(!$response->success) {
wc_add_notice('Please verify that you are not a robot' ,'error');
add_action('woocommerce_checkout_process', 'doublee_process_recaptcha');
wp_enqueue_script('recaptcha', '//', '', '', true);
