What it does
Use when a user mentions "AI action approval queue", "human-in-the-loop workflow", "AI approval gate", or asks for related help. High-value AI-suggested actions (auto-email to high-ARR account, mass account update, large segment send, AI-classified routing decisions) pause for human approval before execution. Slack-based approval. The Relay-style HITL pattern that combines AI scale with human judgment.

How it works
Build the HITL Approval Workflow
Create WorkflowCreate a workflow
Webhook Receives Pending AI Action
configure_webhook_stepConfigure webhook trigger that other workflows call when they want to queue an action for approval. Payload schema: action_type (send_email / update_records / route_lead / make_decision), action_summary (one-line description), full_payload (the actual action data), requesting_workflow (originator), threshold_reason (why this needs approval — high-ARR / large-segment / low-confidence).
Branch by Action Type
configure_workflow_multi_split_stepMulti-split by action_type: send_email → marketing lead approval; update_records → RevOps approval; route_lead → sales manager approval; make_decision → varies by decision type. Each routes to the right approver Slack channel. The approver matters — wrong approver leads to bottlenecks.
Slack Approval Prompt
configure_slack_stepConfigure Slack step that posts an interactive approval message to the right channel/user. Message includes: action summary, originator workflow, threshold reason, action preview (e.g. for email: subject + first 200 chars), and Approve/Reject buttons (or Slack thread-reply
Wait Until Approval
configure_workflow_wait_until_stepConfigure wait-until step that pauses workflow execution until approval response received. Timeout: 4 hours (configurable — high-ARR sends might warrant 1hr, routine updates might allow 24hrs). On timeout: default-reject (safer than default-approve) + post
Branch on Decision
configure_workflow_branch_stepBranch step on the approval decision: APPROVED → execute action (webhook back to originator workflow with
Approved Path: Execute and Log
configure_webhook_stepConfigure webhook call back to the originator workflow to proceed with the queued action. Include approval metadata (approver name, timestamp, any approver comments). Log to audit trail — every AI action that went through approval is fully traceable for compliance + later review.
Rejected Path: Log Learning
configure_update_attribute_stepOn rejected branch: write the rejection to a structured learning log — which AI suggestions are humans rejecting, what
Validate and Publish
publish_workflowValidate and publish. Monitor: approval volume per week, approval-rate (target: 80%+; below 60% suggests upstream AI workflows need tuning), median time-to-decision (target: under 30min during business hours), timeout rate (high = wrong approvers or low-engagement channel). The dashboard for responsible AI governance.
