Need each response to be numbered

Hello All,

I am trying to set up automated emails that trigger on type form submission. I have zappier set up and it all works great. The only thing I need is a way for each automated email to send a unique number that will be the customer id. I have tried everything i can think of. Sending the submission token, but then I don’t have access to that inside of typeform. Setting the number of responses but type form does not save the individual response number in the data, just shows it on home of form with ‘x number of people have filled out this form’. Any ideas?

Thank you
