Yes, I used WP Rocket, but even when I de-activated WP Rocket, I still had the same problem. Have you done tests with WP Rocket activated? As well, it is installed on a Cloudways site. Do you know if this has been reported on any other Cloudways installs?

Thanks,

Kyle

Thanks, will do next time. I figured this one out:

function my_custom_wc_api_order_response( $order_data, $order, $fields ) {
  $customer_info = get_post_meta( $order->id, '_customer_info', true );

    $order_data['payment_details']['customer_info'] = $customer_info;

  // Apply filters if necessary
  if ( $fields ) {
    $order_data = WC()->api->WC_API_Customers->filter_response_fields( $order_data, $order, $fields );
  }

  return $order_data;
}

add_filter( 'woocommerce_api_order_response', 'my_custom_wc_api_order_response', 10, 3 );
