Conversion Tracking code location

Hello there,

I have enabled your plugin “Woocommerce Adwords Conversion Tracking” for site: surffinco.com to get conversation data in adwords. However, my client is getting email from google support that code is not in the right place. I’ve set up the plugin as you guys suggest. But according to google team it is not putting code in between body tags. Could you please give me a few details where exactly it places the code and its functionality part so that I could share same info with my google adword team?

Thanks.
