n8n Vinted Listing Inspector + Google Sheets/Slack/Notion Logging

Preview bounded Vinted listings—then log receipts to Google Sheets, Slack, Notion (with explicit approval)

This n8n workflow inspects bounded sample Vinted listing results for Ralph Lauren, Dior, Sezane, or a custom search, generates readable listing “receipts,” and then previews the proposed rows/messages before any write or delivery. The default first execution prepares input without credentials, source requests, or destination writes.

What this workflow does

• Reads customer fields on demand: A manual trigger captures eight common customer fields, while an Advanced controls node retains source modes, approval phrases, and lowerable resource ceilings.
• Supports safe AUTO configuration: If no completed run ID exists, AUTO prepares the selected search and returns a readable configuration receipt—without HTTP, credentials, or writes. AUTO never starts a paid search.
• Recovers from an exact completed run: When a matching completed run ID is provided, the workflow selects recovery; without that ID, it won’t execute paid requests.
• Verifies Apify Actor/build and payload: For listing previews, three Apify read nodes confirm the exact Actor/build, terminal status, original stored input, and resource/cost guards, then validate the versioned results payload.
• De-duplicates and preserves warnings: The workflow removes exact duplicate source rows, preserves partial/capped warnings, and prepares full listing receipts. Asking prices do not establish sale value or profit.
• Stops for preview and approval: PREVIEW shows the selected target and proposed content, then stops before every destination writer. An explicit approval is required for any write or delivery.
• Writes with completion-order safety (Sheets path): For Google Sheets, it reads before writing, appends missing observation receipts, verifies them, and writes the run completion marker last—skipping duplicate writes during an exact completed replay.

Use cases

• Automation engineers testing Vinted ingestion pipelines with bounded samples and predictable resource/cost limits.
• SaaS operators generating standardized listing receipts for internal review before logging to Slack or Notion.
• Teams validating preview outputs in n8n before committing rows to Google Sheets.

Technical details

• n8n nodes: if, set, code, no op, Slack, Notion
• Destinations: Google Sheets preview/append (with last-step completion marker), Slack, Notion, and email (preview-stopped with explicit approval)
• Core behavior: recovery via completed run ID, Apify read-node verification, duplicate removal, capped-warning preservation, preview-before-write design
