Get Slack Alerts When a Competitor Changes Their Price
DiffScout monitors competitor prices every 30 minutes and posts alerts directly to your Slack channel — with the old price, new price, percent change, and a screenshot link.
Slack alerts on Business plan ($99/mo) · Email alerts on free + Pro plans
What lands in your Slack channel
Payload includes monitor name, old price, new price, % change, timestamp, and screenshot link. Format with Slack Block Kit or route through Zapier/Make.
Set up in 4 steps
No Slack app to install. No OAuth. Just a webhook URL.
In your Slack workspace: go to Settings > Apps > Incoming Webhooks > Add New Webhook to Workspace. Select the channel where price alerts should post. Copy the webhook URL provided.
In DiffScout (Business plan), go to Settings > Integrations > Webhooks. Paste your Slack webhook URL. Optionally add a custom name. Click Save and test — DiffScout sends a test payload to confirm it works.
Paste any competitor product page URL. Describe the specific product or variant to track ("Vital Seamless Shorts, Black, Small"). Set your check frequency — Business plan checks every 30 minutes.
When DiffScout detects a price change, it posts the structured alert to your webhook. No manual checking required. Your team sees every competitor move in the channel they already live in.
Total setup time: ~6 minutes. After that, DiffScout runs automatically — checks every 30 minutes, posts to Slack only when a price actually changes.
How teams use Slack price alerts
Monitor all key competitors. When an alert fires on Friday afternoon, the paid media team can update ad copy before the weekend traffic peak.
Track hero product pricing across the category. Get a real-time picture of where you stand without anyone opening a browser tab.
Spin up a dedicated BFCM channel. Set all competitor monitors to 30-min frequency. Get flash sale alerts as they happen during the highest-stakes week of the year.
Track SaaS competitor pricing page changes. Know the moment Stripe, HubSpot, or a direct competitor adds a tier or changes a plan price.
Need custom formatting or other destinations?
