Cashback Boost Monitor — Rate Change Alerts

Get told the moment a cashback rate changes for the stores you care about: "Nike on Rakuten: 2% → 10%", "Walmart now on TopCashback", "ASOS cut from 5% to 3%".

Cashback portals boost rates for a day or two at a time, often without much notice. This Actor watches your list of stores on Rakuten, TopCashback, BeFrugal, Capital One Shopping, Mr. Rebates and ShopBack across the US, UK and Australia. Each run returns only what changed since the last run. Put it on a schedule and connect it to email, Slack, Telegram, Discord or a webhook, and you have a cashback alert feed.

What you can do with it

• 🔔 Personal alerts: know when your favourite stores are boosted before you buy.
• 📣 Deal channels and newsletters: a steady feed of "cashback boost" posts for Telegram, Discord, X or email.
• 📊 Market tracking: see how often each portal boosts and cuts rates for a set of stores.
• 🤖 Automations: trigger a Zapier or Make scenario whenever a store crosses a rate you care about.

How it works

1. First run: saves the current rate for every store and portal as a baseline. Boosts the portal flags itself (Rakuten's "10% Cash Back, was 2%") are reported straight away.
2. Every later run: compares with the previous run and returns one row per change.
3. Schedule it: hourly or daily in Apify Console (Schedules). Keep the same store list and watchlist name.

Rates are remembered in a key-value store named cashback-boost-monitor-state in your own Apify account, one record per watchlist.

Change types

changeType	Meaning
increase	Rate went up since the last run
portal-boost	The portal itself shows a boost ("was 2%"), reported once per boost
new	The store started offering cashback on this portal
decrease	Rate went down
removed	The store stopped offering cashback on this portal
changed	Switched between a percentage and a fixed amount

Rate increases and decreases are reported on the first run that sees them. A store appearing (new) or disappearing (removed) is reported once it has been seen on two runs in a row, because portals occasionally serve a page without the cashback block and a single odd reading would otherwise be a false alarm. Temporary errors (timeouts, blocks, outages) are never reported as changes; the last known rate is kept until the portal can be read again.

Pricing

Pay per change: you are only charged for changes reported. Runs where nothing changed cost nothing beyond Apify's small platform usage. If a run hits your maximum cost, the changes it could not report are reported on the next run.
