Groq Testimonial Miner n8n Webhook for Polished Quotes

Turn Customer Reviews Into Polished Testimonials—Automatically

Meet the Groq Testimonial Miner n8n Webhook for Polished Quotes: an n8n automation that accepts a batch of customer reviews via a POST webhook, uses Groq’s OpenAI-compatible Chat Completions API to pick the strongest testimonial quotes and lightly polish them, then returns a clean, structured JSON response ready for your site or app.

What this workflow does

• Receives reviews on the /testimonial-miner webhook with a JSON body containing a reviews array (and optionally a goal).
• Normalizes input and builds a chat prompt instructing the model to output only a JSON object containing the best testimonial quotes plus a short one-line summary and rating stats.
• Calls Groq using the openai/gpt-oss-120b model with JSON response formatting enabled.
• Parses and validates the returned JSON, filtering out invalid testimonial entries.
• Returns organized results including: source_count, top quotes, summary, rating_avg, and total_counted.

Use cases

• Generate “Top Testimonials” for a landing page from a stream of reviews.
• Select the strongest quotes for SaaS product pages without manual review-by-review sorting.
• Create consistent testimonial excerpts for case studies and email campaigns.
• Run periodic review mining jobs with an n8n webhook call from your app or admin tools.

Technical details

• n8n nodes: webhook, if, code, http request, respond to webhook.
• Groq integration: HTTP header auth with your Groq API key configured as an n8n credential for the HTTP Request step.
• Endpoint: expose the workflow webhook URL and POST to /testimonial-miner with a JSON payload containing reviews.

Perfect for n8n users and automation engineers who want reliable, structured testimonial mining using Groq’s OpenAI-compatible Chat Completions—directly through a webhook.
