The Human-in-the-Loop (HITL) integration brings human oversight and intervention into AI-driven Workflows. It allows members of your Workspace to:
  • Chat directly with users
  • Approve AI-generated outputs before they’re sent
  • Handle complex or sensitive scenarios

  2. Add the Start HITL Card:

  1. Fill in the required fields:

Publish and test your bot

First, let’s simulate a user escalation.
HITL won’t work in the Emulator—you’ll need to test it using Webchat.
  1. Publish your bot and open the Webchat preview window.
  2. Chat with your bot until it begins HITL:
