I check for new order in WOO commerce and want to copy some fields to Airtable. Sometimes a customer doesn’t seem to have a customer_id. I want to check this, but tried several formulas without succes. It seems to be empty, but how can I check this.
I have something like if (customer_id=null ; 1.email_adres ; customer_id)

What is the right formula?

Hey there,

its ifempty(), but I dont see why your if formula shouldnt work either. Just make sure you are using the tag {{null}} and not the text string null.
