A free n8n template to sync supplier stock and prices to Shopify (with dry-run mode)

Description and use

An n8n automation template that syncs supplier stock and prices to Shopify with dry‑run mode, safety checks, and Slack notifications.

Problem

Small Shopify stores that resell or dropship manually download supplier stock and price files and update Shopify, risking out-of-stock sales or manual errors.

Outcome

The template automates supplier stock and price sync to Shopify, reducing manual effort, preventing out-of-stock sales, and providing dry‑run safety checks and Slack alerts.

Workflow

• Configure shop URL, location, feed URL, column names and pricing rules
• Get Shopify token via client ID/secret
• Download supplier feed (CSV/JSON)
• Fetch Shopify variants by SKU, price and stock
• Build sync plan matching feed to variants and calculating price
• If dryRun is true, report only; else send updates to Shopify and check results
• Send Slack summary of changes
• Post to Slack on production run failure
