I have gone through your tutorial and followed your

I have gone through your tutorial and followed your instructions from uploading the key to sharing with the google service account on the calender but I cannot seem to get the appointment to show up on the clients google calender. When I test it there is no alert saying what wrong but that test appointment does not show up either. So I don't know what to fix. It seems to see the calender and shows blocked times and an email goes to the client if I make an appointment. But they need it to go onto the calender. Help please
