Autopopulating ZC fields with Zoho CRM Data

Autopopulating ZC fields with Zoho CRM Data

Hello, I am trying to set up a form in Zoho creator where you input the Unit Number and from that it autopopulates other fields in the creator form (i.e., VIN, Year, License Plate). And it needs to go into CRM and by the unit number entered get the correct values. I cannot seem to figure this out. I have tried getrecordsbyID but I cant understand how to find the Record ID from the Unit Number? Any help would be greatly appreciated.
