On a schedule, the Browser scrapes the product price using the name: selector pair you set (point it at an element showing a plain number such as 499.00); a Branch compares it with your target as a whole number and alerts Slack on every check while it is below the target, otherwise logging the check to a sheet.

How this workflow runs

What happens at each step once the workflow is on, and what you need before you import it.

Step 1Trigger
Schedule Every X Hours
This workflow runs on a schedule (Every X Hours) — it starts on its own at the interval and time you set in the Schedule trigger. No incoming event is needed.
Step 2Action
FlowMattic Browser Scrape Content by Selector
FlowMattic Browser — extract text values from a URL using CSS selectors. Ideal for pricing intel, job boards, real-estate feeds → Google Sheets. Data is mapped from earlier steps; connect your FlowMattic Browser account on import.
Step 3Logic
Branch Price below target?
The Branch evaluates "Price below target?": when it's true the Yes path runs, otherwise the No path runs — two outcomes, one workflow.
Step 4Action
Slack Send Channel Message
On the Yes path (condition met) — Slack — post or Schedule a new message to a specific #channel. Data is mapped from earlier steps; connect your Slack account on import.
Step 5Action
Google Sheets Add New Row
On the No path (otherwise) — Google Sheets — trigger when a new row is added to the spreadsheet. Data is mapped from earlier steps; connect your Google Sheets account on import.
