How to verify if variable value is blank when setting branching rule?

(0) ShareShare

Posted on by 15

I need hide questions when a variable that is passed from Power Automate to Customer Voice is not set, or blank, or null.

How do I do that? Everything I type in the branching rule screen is considered as text.

Thank you.

    Is there an answer to this? It will not allow checking for an empty string as a trigger in advanced logic.

    Why don't you set an initial dummy value to the variable in power automate?

    Then instead of checking for null in CustomerVoice, you may check for this specific value

    So it gets up to Power Automate (with a if card) to check for null value and replace it with whatever you want, before calling the Survey

    This seems so obvious now you've said it! Thanks for your help that will work great!
