FINRA API Developer Center is implementing a warnings capability to provide warnings when sensitive data are found in a free text field in U4. Every field with a "warnOn" attribute in the U4 schema will be analyzed for the presence of sensitive data. 

Details: 

• GET Submission API calls will return a new attribute called "warnings" with a list of warning(s) if any sensitive data is included in a free text field in U4 submission. If there are warnings for the filing, the submission will fail. 
• A new flag ignoreWarnings will be provided to be included in the U4 POST Submission metadata, if needed. Setting ignoreWarnings = true will bypass the warning(s). The default value for ignoreWarnings will be false. If ignoreWarnings = true is provided, the GET Submission call will return an empty warnings array, even if sensitive data are found in some of the fields. 
• Sensitive data includes SSN, DOB, Tax ID, Health Information.
• U4 schemas (both POST and GET) have been updated with the new attributes. See U4 Dataset details for more information.   
• Timeline for change 
  • QA Test: 3/31/2025 
  • PROD: 6/27/2025 evening
