Nothing can be found for the search Smartsuite

Hello Guys,

I send a webhook from GHL and search for the record in SmartSuite base, I want to have a scenario when nothing can be found for the search I want to create a new record in SmartSuite if the record was found just update the single select, I can’t find out the way to do it and which modules to use, I tried with filters but no luck, if anyone has the solution please let me know, thanks in advance and kind regards <3
