Summarize Webhook Form Submissions with OpenAI & Slack Alerts

Instant AI summaries for every form submission—sent straight to Slack

This n8n workflow receives webhook-based form submissions, uses OpenAI to generate a one-sentence summary with an urgency rating, and posts a clean alert to your chosen Slack channel—so your team can triage leads and requests faster.

What this workflow does

• Receives submissions via an n8n webhook: Your form provider sends a POST request to the workflow trigger.
• Normalizes incoming fields: The workflow standardizes common contact and request data into consistent fields such as name, email, company, request type, and message.
• Summarizes with OpenAI Chat Completions: It sends the submitted message text to the OpenAI Chat Completions API to produce a one-sentence summary and an urgency level.
• Posts to Slack: It publishes a formatted alert containing requester details and the AI-generated summary. If no summary is returned, it falls back to the original message.

Use cases

• SaaS lead intake: Summarize new inbound requests and route urgent items to sales or support via Slack.
• Support request triage: Turn form submissions into quick AI summaries with urgency signals for faster response.
• Website/landing page feedback: Monitor “request type” and message content in one Slack stream for the whole team.

Technical details

• n8n nodes: webhook, set, http request, slack, and a sticky note for guidance.
• OpenAI integration: Add your OpenAI API key by replacing the placeholder Authorization header used for the OpenAI Chat Completions request.
• Slack integration: Connect Slack credentials in n8n and set the target channel (e.g., #new-leads).
