​
Overview

Human Tasks are designed for workflows that require human intervention, such as approvals, reviews, or decision-making. These tasks pause the workflow execution until human input is received.

​
Configuration Structure

{
  "type": "HUMAN_TASK",
  "block": {
    "name": "Human Task Name",
    "type": "HUMAN_TASK",
    "instructions": "Based on the given message, categorize the message into APPROVED or REJECTED or UNDECIDED",
    "dependencies": [],
    "error_policy": "RAISE",
    "assignment_type": "USER", // Required: USER or TEAM
    "assignee_id": "user_id", // Required: User ID or Team ID based on assignment_type
    "assignment_logic": "Round_Robin" // Required only when assignment_type is TEAM
  }
}

​
Task Instructions

Human tasks require clear instructions for the assigned user or team. Instructions should:
  • Be specific and clear
  • Define expected actions
  • Provide decision criteria
  • Include any relevant context
Example: 
{
  "instructions": "Review the generated content for accuracy and alignment with brand guidelines. Choose APPROVE if content meets all criteria, REJECT if changes are needed, or UNDECIDED if further review is required."
}

​
Assignment Rules (Required)

When creating a Human Task, you must configure an assignment rule to specify who will be responsible for completing the task. Without a valid assignment rule, you will not be able to create or update the workflow.

​
Assignment Configuration

{
  "rule_type": "Human Feedback",
  "assignment_type": "USER|TEAM", // Required: Must be either USER or TEAM
  "assignee_id": "id", // Required: User ID or Team ID based on assignment_type
  "assignment_logic": "Round_Robin|LRU" // Required only when assignment_type is TEAM
}

​
User Assignment

When assigning to an individual user, select “USER” as the assignment type and choose from the dropdown list of users in your organization. 
{
  "rule_type": "Human Feedback",
  "assignment_type": "USER",
  "assignee_id": "user_id" // Selected from organization user list
}

​
Team Assignment

When assigning to a team, select “TEAM” as the assignment type, choose a team from the dropdown list, and specify an assignment logic. 
{
  "rule_type": "Human Feedback",
  "assignment_type": "TEAM",
  "assignee_id": "team_id", // Selected from organization team list
  "assignment_logic": "Round_Robin" // Must specify either Round_Robin or LRU
}

​
Assignment Logic Options

  • Round_Robin: Distributes tasks evenly among team members in a circular sequence
  • LRU (Least Recently Used): Assigns task to the team member who has not been assigned a task for the longest time
Important Note: If assignment rule conditions are not properly configured, you will not be able to create or update the workflow. All required fields must be completed with valid values.

​
Common Use Cases

​
1. Document Approval

{
  "name": "Review Document",
  "instructions": "Review the attached document and approve or reject based on compliance guidelines",
  "dependencies": ["Generate Document"]
}

​
2. Content Review

{
  "name": "Review Content",
  "instructions": "Review the AI-generated content for accuracy and brand voice. Provide feedback if changes are needed.",
  "dependencies": ["Generate Content"]
}

​
3. Decision Making

{
  "name": "Process Decision",
  "instructions": "Review the analysis results and decide on the next steps. Choose APPROVE to proceed or REJECT to revise.",
  "dependencies": ["Analyze Data"]
}

​
Task Flow

​
Response Types

Human tasks can have three possible responses:
  1. APPROVED: Task approved, workflow continues
  2. REJECTED: Task rejected, requires revision
  3. UNDECIDED: Additional review needed

​
Best Practices

​
1. Instructions

✅ Do:
  • Write clear, concise instructions
  • Specify decision criteria
  • Include relevant context
  • Define expected outcomes
❌ Don’t:
  • Use technical jargon
  • Write vague instructions
  • Omit important details
  • Assume knowledge

​
2. Assignment Rules

✅ Do:
  • Set appropriate assignees
  • Configure backup assignments
  • Use team assignments for shared tasks
  • Set reasonable deadlines
  • Verify all required fields are completed
❌ Don’t:
  • Assign to inactive users
  • Skip backup assignments
  • Ignore time zones
  • Use overly complex rules
  • Leave assignment rules incomplete

​
3. Dependencies

✅ Do:
  • Clearly define prerequisites
  • Verify data availability
  • Set proper task order
  • Handle all outcomes
❌ Don’t:
  • Create circular dependencies
  • Skip validation
  • Ignore error cases

​
Error Handling

​
Configuration

{
  "error_policy": "RAISE",
  "notification_channels": ["email", "slack"],
  "escalation_after": 24 // hours
}

​
Common Scenarios

  1. Timeout
    • Task not completed within deadline
    • Automatic escalation
  2. Assignee Unavailable
    • Automatic reassignment
    • Backup assignee notification
  3. Invalid Response
    • Validation error
    • Request for correction

Integration Examples

​
With AI Task

{
  "name": "Review AI Output",

  "dependencies": ["Generate AI Content"]
}

​
With App Task

{
  "name": "Approve Document",
  "instructions": "Review and approve the generated document",

}

​
Notifications

​
Assignment Notification

{
  "channel": "email",
  "template": "task_assignment",
  "data": {
    "task_name": "Document Review",
    "instructions": "...",
    "deadline": "2024-02-24T15:00:00Z"
