HITL Support Reply Agent
This template shows Heym's Human-in-the-Loop (HITL) flow on an Agent node. The agent drafts a customer response, calls request_human_review, exposes a review link on the HITL branch, then resumes after the reviewer accepts, edits, or refuses the draft.
What this workflow does
- CustomerRequest provides a sample support escalation
- DraftReplyAgent prepares a customer-ready response and requests human review before finalizing it
- NotifyReviewSlack sends the pending review URL, summary, and Markdown draft to Slack from the HITL branch
- ApprovedReply returns the final reviewed reply and decision metadata after the run resumes
Use cases
- Customer support replies that need manager approval
- Refund, escalation, or legal-sensitive response review
- Portal workflows where a human should approve an agent action before it reaches a customer
Setup
Connect an LLM credential in the Agent node and a Slack credential in NotifyReviewSlack. Run the workflow, open the generated review URL from Slack, then accept, edit, or refuse the draft to resume execution.
Notes
HITL works with text-mode Agent output. Keep JSON output disabled on the Agent node when using this template.
