Course 1: MIFY Fundamentals — Chapter 4

Chapter 4: Human Approval Gates

Section titled “Chapter 4: Human Approval Gates”

Not everything should be fully automatic. Learn to add checkpoints where a real person reviews the AI’s work.

What You’ll Learn

Section titled “What You’ll Learn”
  • How Human-in-the-Loop (HITL) works
  • How to add approval gates to workflows
  • How to review and approve/reject from the Inbox

Why Approval Gates?

Section titled “Why Approval Gates?”

Some examples where you want a human to check before proceeding:

  • AI drafts an email → manager approves → email is sent
  • AI extracts contract terms → legal reviews → data is saved
  • AI generates a report → director approves → report is distributed
  • AI makes a recommendation → specialist verifies → action is taken

Adding an Approval Gate

Section titled “Adding an Approval Gate”
  1. Open a workflow on the canvas
  2. Drag a Pause node from the HITL category
  3. Place it between the AI node and the next step
  4. Connect: AI Node → Pause → Next Step
Trigger → Chat (AI drafts) → Pause (human reviews) → Send Email

When the workflow reaches the Pause node, execution stops and waits for a human decision.

Reviewing in the Inbox

Section titled “Reviewing in the Inbox”

Pending approvals appear in your Inbox at /inbox:

MIFY Inbox — pending approvals

For each pending item, you see:

  • What workflow is waiting
  • What the AI produced
  • How long it’s been waiting

You have two options:

  • Approve → execution continues to the next step
  • Reject → execution stops

Automatic Escalation

Section titled “Automatic Escalation”

If nobody responds within the configured time, MIFY can escalate:

  • Send a reminder notification
  • Escalate to a different channel (email, Slack)
  • Auto-approve or auto-reject after timeout

Exercise

Section titled “Exercise”
  1. Use the “Guardrailed HITL Approval” template from the Solutions Library
  2. Run it — the AI generates content and pauses for your review
  3. Go to your Inbox
  4. Review the generated content
  5. Click Approve or Reject
  6. Check the Runs page to see how the execution completed

Key Takeaways

Section titled “Key Takeaways”
  • Pause nodes stop execution and wait for human input
  • The Inbox shows all pending approvals across all workflows
  • Escalation ensures nothing sits waiting forever
  • HITL is essential for compliance and quality control
