        "content": "## Analyze OfferUp used car and VIN deals with OpenAI and alert Slack, Telegram, and Sheets\n\n### How it works\n\nThis workflow runs every six hours to extract fresh records through the **[offerup-vehicles-cars-scraper](https://apify.com/unitbytes/offerup-vehicles-cars-scraper?fpr=939u3w&fp_sid=n8n_io)** UnitBytes Apify actor ($0.0008 / item), remove previously seen items by `listingId`, and normalize and score the dataset (`listingId, url, title, price`). It maps the cleaned fields for export, logs all rows to **Google Sheets**, creates a backup **CSV** file, and sends only high-priority records into **OpenAI (`gpt-4o-mini`)** for structured analysis and action drafting. The enriched fields are then merged and delivered to **Slack** and **Telegram**.\n\n### Setup steps\n\n- Configure the schedule interval in **When Every 6 Hours** if six hours is not ideal for your cadence.\n- Add your Apify API token from [offerup-vehicles-cars-scraper on Apify Store](https://apify.com/unitbytes/offerup-vehicles-cars-scraper?fpr=939u3w&fp_sid=n8n_io) (`Authorization: Bearer <YOUR_APIFY_TOKEN>`) in **Post to OfferUp Used Cars, Vehicles & VIN Scraper: Dealer Specs API** and confirm `actorInput` in **Set Search Parameters**.\n- Connect **Google Sheets** credentials in **Append Data to Sheets** and select your destination spreadsheet.\n- Configure **OpenAI** credentials in **AI Sourcing and Arbitrage Analyst** and review the `gpt-4o-mini` system prompt.\n- Connect **Slack** and **Telegram** credentials on the final delivery nodes.\n- Review `maxTargetPrice` and `priorityKeyword` in **Set Search Parameters** before activating.\n\n### Customization\n\nAdjust `actorInput`, `maxTargetPrice`, `priorityKeyword`, the OpenAI prompt, Slack message formatting, and Telegram template fields to match your workflow.
