Its just as Robert said, but here is the steps if it helps
Start with your date slot like so

Then Create your string variable like so

The expression would look like this
Append(ToString(Day(Slot.StartDate)), ".", ToString(Month(Slot.StartDate)), ".", ToString(Year(Slot.StartDate)))
Click on the variable name and set it to Output from Flow

And now it in the calling flow you will see it under outputs just like the slots.

Hello Anton, thank you for your answer. I don't want to burden you too much, but would it be possible for you to show me how the variable has to be written so that it works as well as the built-in one?

You will need to setup your own string variable to do that conversion, and then set that new variable as an output, and then you can access it like any other output in the calling flow.

Hi Robert, thank you. I could not figure it out and It seems to me the problem is that the slot result in the bot is date and the outputs in the call bot action are all string and I can´t change it to anything else then string. I don´t know how to make that matching.

If you are getting a date format, you can use Append(Day(datetimevariable), ".", Month(datetimevariable), ".", Year(datetimevariable)) to create a string with that format. If all you are getting is a string, you will need to convert that string to a datetime type using MakeDate(datetimevariable). Again, you might have to break the string down for the MakeDate to work.

Next question :-) I collect date of birth in a voice bot and it appears as e.g. 1980-01-21 in a call script. How can i convert this date format that it appears as 21.01.1980? I would rather do it in the flow than in the script.
