Both, depends
Any data type with appropriate privacy rules will be hidden from the user.
So, you might have a data type API Call with privacy rules such that only the admin can see it, and the API Call has a User field, date, and whatever ‘variable’ you want. I don’t really understand your specific use case but if you want to delay storing it then you can do it with Schedule API workflow and creating it at a future date…
Can’t you just:
- Track users answers on page
- Schedule API workflow and pass answers to API workflow parameters
- Create the thing in the backend which tracks the API call
If you need to return data from the backend to the user, then do the same but use this method: Log in "as a user" - but be careful. Admin usage - #6 by georgecollier
