How can I get a unique ID when I submitted an answer in Google Form?

Question

I am using Google Form for my customers to submit their opinion. I read this and this, but I have some questions which these two posts haven't mentioned.

Is it possible for my customers to know their submission ID when they see the confirmation page?

E.G.:

Thanks for your response. Your reference no. is #S201501. We will contact you within 7 days.

The second customer will have #S201502… etc.

Can I also check the reference no. in my original spreadsheet?

Answer 1

There is no way to dynamically change the confirmation/thank you message. However, you could use the Autocrat add-on (or adapt its code) to send your customers a confirmation email with the reference number.
