Page Validation Rules
The Validation Rules page lists all validation rules configured for a specific integration field. Each rule defines a data quality condition that is evaluated during import or export. Rules with Error severity block rows that fail; rules with Warning severity flag rows but still allow them through.
To open: From the Integration Fields page, select a field and choose Validation Rules from the action bar. Or click the Has Validation Rules indicator on the field row.
Overview
See How to Set Up Validation Rules for a full configuration walkthrough and descriptions of all 11 rule types.
