Smart Action validation

Hi :wave:t2:,
I want to validate fields in smart actions and show a message to the user if the fields are not valid.
How can I do this?

Thanks in advance
Bernhard

Hi @bef !
You can send a custom response upon execution (check the fields on the backend and send an error if they are not valid) or you can use the change hook to check them in real time (and maybe use a readOnly Field that displays an error when you need it to do so).

Hi @Nicolas_Sailly
I saw the custom response solution. But I was wondering if there is a way to mark an input field if or something like that.
But the custom response will do the job :slightly_smiling_face:
Thanks for your help.
