The exact six-node n8n workflow from our Shopify API authentication guide. It calls the Shopify Admin API on a schedule using your stored credential, checks the response, and alerts Telegram the moment authentication breaks, so a revoked token never fails silently.
- Custom app access token and OAuth2 both supported via the native Shopify credential
- HTTP Request reuses your Shopify credential to reach the shop.json endpoint
- Never-Error handling so a 401 is caught, not crashed on
- Telegram failure alert with the status code and error body
- Works on n8n Cloud and self-hosted, credentials pre-slotted
