I have a field on a form that should only be updated in Saleforce if the field is blank.  The field on Contact, Origin Code, can be applied to new or existing Contacts, but only if there is not an Origin Code already in the field.  Is this possible?

You can use a Filter to detect if a field value exists or does not exist and proceed accordingly: https://zapier.com/apps/filter/help

Thank you!  Does the task that follows the filter need to be the last step in the process?  I will need to update the record with all fields, then filter based on the one field being blank, then update the records with that field, but then I have one more step (add to campaign).  Should I move that step above the the update record step?

Hi @Start Early 

The order of Zap steps will depend on what logic you are trying to apply, so keep in mind the order of operations with the different apps and data involved.
