How to add Google Ads conversion purchase event to my Thank you Page

Hi,

This is what my functions.php file looks like. I hid my site with ” ********* ”

//Auto Complete Processing WooCommerce orders on Thankyou Page

add_action( ‘woocommerce_thankyou’, ‘custom_woocommerce_auto_complete_order’ );
function custom_woocommerce_auto_complete_order( $order_id ) {
if ( ! $order_id ) {
return;
}

$order = wc_get_order( $order_id );
if ( $order->has_status(‘processing’) ) {
$order->update_status( ‘completed’ );
}

}

// Redirect WooCommerce checkout page to ******************** after the payament
add_action( ‘woocommerce_thankyou’, ‘pfwp_redirect_woo_checkout’);
function pfwp_redirect_woo_checkout( $order_id ){
$order = wc_get_order( $order_id );
$url = ‘https://*********/*********/*********/’;
if ( ! $order->has_status( ‘failed’ ) ) {
wp_safe_redirect( $url );
exit;
}
}

And I want to add the Event snippet inside the Thank You for google ads.

<!– Event snippet for Purchase conversion page –>
<script>
gtag(‘event’, ‘conversion’, {
‘send_to’: ‘AW-***********/********kDENy8vL4o’,
‘value’: 1.0,
‘currency’: ‘SAR’,
‘transaction_id’: ”
});
</script>
<!– End Event snippet for Purchase conversion page –>

Because I am redirecting the thank you page to another page, the script will trigger? Or not?

And how and where do I add the Event snippet at the functions.php because I have a lot of code that controls WooCommerce?
