Clay's Update Record action for Salesforce overrides fields by default. However, you can control this behavior with the "Remove Blank Values" setting:
** True: Blank values from Clay are ignored, preserving existing Salesforce data
** False: Blank values will overwrite existing Salesforce values
This setting prevents accidental data loss when updating records.
Hey Sarah! Thanks for reaching out. It will overwrite the data in the field. if the data is the same, it looks like it stayed the same but it is actually overwritten. This is visible in fields where the data actually changed.
Hope that helps!
