Price Drop & Restock Monitor - Any Store + Discord/Slack

Track the price of any product in any online store and get an alert the moment the price drops or the item is back in stock. Alerts go to Discord, Slack, Telegram or any webhook (Zapier, Make, n8n). Schedule it hourly or daily and it keeps a full price history for you.

Why use it

• Any store: Shopify, WooCommerce, Magento, BigCommerce and most modern shops (reads the real price from the product page's structured data)
• Price drops, increases, restocks and sell-outs compared with the previous run
• Price history: lowest and highest price seen, "lowest ever" flag
• Alerts anywhere: Discord, Slack, Telegram or JSON webhook
• Separate watchlists: one actor, many product lists
• No browser, no login, fast and cheap

Who it's for

E-commerce sellers watching competitors, repricing and arbitrage, deal hunters and deal sites, procurement teams, dropshippers.

Quick start

1. Paste product page URLs into productUrls.
2. Add a Discord/Slack webhook, Telegram bot, or a Zapier/Make webhook.
3. Run once (the first run saves the current prices), then Schedule it. Every next run reports only real changes in the alert.

FAQ

Which stores work? Any store whose product pages include standard product data (most do). Some marketplaces block automated access; Apify Proxy is on by default. Where is the history kept? In a named key-value store in your Apify account, per watchlist.

Use it as an integration (chain it after another actor)

This actor can run automatically after any actor whose results contain a URL.

1. Open the source actor in Apify Console and go to the Integrations tab.
2. Click Add integration -> Actor, pick this actor and set Dataset to {{resource.defaultDatasetId}} (leave productUrls empty). Set your other options and save.
3. When the source run finishes, this actor reads its dataset and processes every row. The field is detected automatically; set Dataset field if your column has another name.

You can also start it by hand with datasetId (pick a dataset or paste its ID) to process an existing dataset.
