Watch Walmart Prices and Alert Discord When They Change
On a schedule this scrapes the Walmart product pages you track, compares against the last-seen price, and pings Discord whenever one moves — so you react to competitors' pricing the same day.
- 1
Step 1 — Schedule the scan
Add a
Schedule Trigger(e.g. every 6 hours) then loop over your list of Walmart product URLs. - 2
Step 2 — Fetch the current price
Add an
HTTP Requestnode to load each page and anHTML Extract/Codenode to read the price. Respect the site's terms and a sensible rate limit. - 3
Step 3 — Compare to last seen
Store the previous price (Google Sheet or n8n static data) and add an
Ifnode that only continues when the price has changed. - 4
Step 4 — Alert Discord
Add a
Discordnode. Point it at a channel webhook and paste the product, old price, new price and link into the content field. Discord webhooks need no OAuth — just the webhook URL from the channel settings.
Frequently asked questions
Is scraping Walmart allowed?
Check Walmart's terms of service and robots rules, and prefer an official API where one exists. Keep request volume low and don't scrape personal data.
The page structure changed and it broke — now what?
Scrapers are brittle by nature. Add a fallback in Step 2 that alerts you when no price is found, so you know to update the selector rather than silently missing changes.
