n8n Workflow: Track Vinted UK Listings & Price Changes to Google Sheets

Track Vinted UK Listing Links & Price/Condition Changes in Google Sheets (With Apify)

This n8n workflow watches a public Vinted UK catalog URL, records the listings it finds into Google Sheets, and keeps your sourcing shortlist up to date with observed price and factual changes—including a stable “upsert” row per listing.

What this workflow does

• Validates inputs before paid work: it checks a public UK catalog URL, a stable watch name, destination, and charge cap.
• Runs a single Apify catalog crawl: starts one Apify run and polls that same run; failed starts are not automatically retried.
• Reads up to 24 listings using the catalog filters, then verifies source coverage, record identities, and accepted billing receipts.
• Labels new and changed observations: first-run matches are marked NEW even if they were posted earlier, and subsequent runs capture factual changes (not guesses).
• Upserts one stable row per listing and watch scope: repeats update observations and add genuinely new matching listings.
• Shows coverage & timestamps: the workflow tracks whether the sample is CAPPED. CAPPED is a bounded sample—not complete inventory—and unseen items are not assumed gone.

Use cases

• Maintain a sourcing shortlist for Vinted UK items and compare observed prices over time.
• Monitor condition/price changes on a curated set of listings using stable Google Sheet rows and timestamps.
• Help buyers and resellers review listing links in one place—without any purchase automation.

Technical details

• Nodes/logic used: if, set, code, wait, sticky note, http request
• Integrations: Apify (via Header Auth using Authorization: Bearer <token>) and Google Sheets (OAuth2)
• Spreadsheet setup: create a “Vinted Watch” tab, import the companion header CSV, and use upsertKey as the only matching column.

Important: This workflow never purchases items and does not predict resale profit.
