Generate Reddit customer leads from a product URL with OpenAI and Firecrawl

Reddit Lead Generator - Frontend Integrated (Productized Version)

Overview

Production-ready Reddit lead generation system with progressive data loading for optimal UX. This workflow integrates with a web frontend, sending results in real-time as they're processed instead of waiting for everything to complete.

Key Features

✅ Progressive Loading - Users see results as they come in (website analysis → keywords → conversations) ✅ 5 Response Stages - Data sent in batches for better UX ✅ Webhook Authentication - Secured with API key headers ✅ Frontend Ready - Built to work with the companion web app ✅ Real-Time Updates - No waiting for 2-minute batch processing

What This Workflow Does

1. Receives product URL from frontend via webhook
2. Immediately responds "processing started"
3. Analyzes website with Firecrawl → sends data to frontend
4. Generates 10 keywords with OpenAI → sends to frontend
5. Searches Reddit and filters conversations → sends in 3 batches
6. Frontend displays results progressively as they arrive

Response Flow

Stage 1: website_analysis - Product details, favicon, summary Stage 2: keywords_generated - All 10 keywords Stage 3: conversations_partial1 - First keyword results Stage 4: conversations_partial2 - Second keyword results Stage 5: conversations_final - Remaining keywords (3-10) in markdown
