I have an integration set up between Zoho Forms and Zoho CRM. Some of the fields of Zoho Forms don't have to be filled, and when people don't the integration don't run from beginning to end. 

I was wondering if I could bypass somehow? See below image of the custom functions and the builder:

I had to set up those custom functions/transitions to convert some of the data in order to be mapped succesfully inside CRM.
