n8n Workflow: Reply to HeyRepli Positive Mentions & Slack Alerts

Automatically reply to HeyRepli positive mentions—and alert your team in Slack

This n8n workflow runs every 15 minutes to pull recent brand mentions from the HeyRepli API, identify positive sentiment, create a HeyRepli draft reply for each, and post a clear notification to your Slack channel with the mention details and the draft reply ID.

What this workflow does

• Runs on a schedule: A schedule trigger starts the workflow every 15 minutes.
• Fetches recent mentions: The workflow requests the latest mentions from the HeyRepli API.
• Filters for positive sentiment: Using an if condition, it keeps only mentions marked as positive.
• Creates draft replies in HeyRepli: For each positive mention, it drafts a reply using the mention text and the post details, creating a draft reply in HeyRepli.
• Sends Slack alerts: It posts to #social-alerts with the author, mention text, and the HeyRepli draft reply ID so your team can track what was prepared.

Use cases

• Customer advocacy at scale: Automatically draft responses for positive brand mentions while keeping humans in the loop via Slack.
• Social media support operations: Reduce manual review time by surfacing only the mentions that are already positive.
• SaaS marketing workflows: Maintain consistent engagement without waiting for end-of-day reporting.

Technical details

Setup requirements
