Inputs

FieldWhat it doesType
productsThe product URLs to track. Each item is an object: { "url": "https://store.com/products/x", "label": "optional human name" }. `url` is required; `label` is optional and used in output and alerts. Best results on pages that expose structured product data (most Shopify / WooCommerce / schema.org Product stores). Marketplaces with heavy anti-bot protection (Amazon, Walmart, eBay, SHEIN) are intentionally NOT targeted — see the README.array
onlyNewSinceLastRunWhen ON (recommended for scheduled monitoring), only products that are new or have changed are emitted to the dataset — deltas, not a full re-dump. When OFF, every product's current state is emitted every run.boolean
trackPriceDetect price_change events (old -> new, with % change).boolean
trackStockDetect back_in_stock / out_of_stock events.boolean
trackSalePriceDetect sale_started / sale_ended events (based on compare-at / list price where the source exposes it — best on Shopify & WooCommerce).boolean
trackTitleDetect title_change events (useful for catching relisted / swapped products).boolean
priceDropThresholdPctOnly treat a price DROP as a change when it is at least this percentage. 0 (default) records every price change. Price increases are always recorded regardless. Use e.g. 5 to ignore tiny fluctuations and only act on meaningful drops.integer
notifyOnRestockSend a webhook notification when a product comes back in stock.boolean
notifyOnPriceDropSend a webhook notification when a price drops (respecting the price-drop threshold above).boolean
webhookUrlOptional. Slack, Discord, or generic webhook to receive a compact change summary. Slack (hooks.slack.com) and Discord (discord.com/api/webhooks) formats are auto-detected; any other URL receives the full structured JSON payload (great for Zapier / Make / n8n / custom endpoints).string
