Pull in discounted Appointments+ price to google calendar


I have some code from Panos which is now working great so that when an customer books an appointment using a coupon code the correct discounted price shows in a confirmation email. As noted in this thread


But I’d like it to also pull this discounted price into the Google Calendar via a shortcode. Ideally if no coupon code is used then only the full price is displayed. Or a N/A for the Discounted Price would be acceptable.

Hope someone can help

Kind Regards
