Summary

Added detailed time format specifications and expanded EDI validation documentation

Security assessment

The update clarifies validation rules for EDI processing, including custom validation checks (e.g., code lists, element requirements). While this improves documentation of security-adjacent data integrity controls, there is no evidence of addressing a specific security vulnerability.

+Specifies whether or not to validate the EDI for this X12 object: `TRUE` or `FALSE`. When enabled, this performs both standard EDI validation and applies any configured custom validation rules including element length constraints, code list validations, and element requirement checks. Validation results are returned in the response validation messages.
