Human validation allows you to pause workflow execution for manual review and approval. This is essential for workflows that require human judgment or verification. ## When to use human validation Use human validation when: * Processing sensitive or high-value documents * Making critical business decisions * Verifying AI extraction accuracy * Compliance or regulatory requirements demand human oversight * Data quality needs manual verification ## Validation types ### Optional validation AI nodes like **Document Extractor** support optional validation: * Workflow continues automatically by default * Can be flagged for human review if needed * Useful for quality checks on a subset of runs ### Mandatory validation The **Manual Validation** node always requires human input: * Workflow pauses at this node * Workflow resumes after approval ## Validation process 1. **Workflow Pauses**: Execution stops at the validation node 2. **Task Created**: A validation task is created 3. **Review Data**: Reviewer examines data and reference documents 4. **Make Corrections**: Reviewer can edit extracted data 5. **Approve**: Reviewer approves and workflow continues ## Validation interface The validation interface shows: * Original document (if applicable) * Extracted/processed data * Expected values for comparison * Edit capabilities for corrections * Approve/reject buttons ## Best practices * Assign validation tasks to specific team members * Set up notifications for pending validations * Monitor validation queue regularly * Document validation guidelines for consistency * Use optional validation for lower-risk items * Reserve mandatory validation for critical data
