Hi Vila
I think you’ll know this part already. Of course using the Google Sheets integration, you can output the answers to each question in a Google sheet that way the sheet holds the Person, their Qs and answers,
… that’s not quite like a log or transcript but i can elaborate there…
-
Your Facebook Messenger page let’s you see the messages which have been sent & received so you can see the full transcript there - but that would only be if your bot was on Messenger.
-
When our Analytics arrives (this is pending) there will be a pane which let’s you view the chat transcript so you can see the logs of what was sent & received I think that will help.
