There is a subset of fields for which there is no field mapping.
These fields do not need mappings because there is code in the HubSpot/Salesforce integration that ensures all portals sync this information - as a result of this, these fields cannot be modified in HubSpot.
The fields that do not require mappings are:
- Lead ID
- Contact ID
- Account ID
- Campaign ID
- Salesforce Owner ID, Name, Email (Salesforce Owner fields map to the Contact owner, Company owner, and Deal owner fields)
