Synthetic monitoring for your Shopify purchase flows

When you install the Shopify app, Revenue Shield generates up to three purchase-flow tests for your store from these flow types:

• Product-page checkout — open a product, select a variant, add to cart, reach checkout.
• Homepage-to-checkout — start on the homepage and navigate through to checkout.
• Buy now — the express path that skips the cart.

Each generated test is validated on desktop and mobile before it goes live, and you review the flows in the app before monitoring begins. If you are new to the technique itself, what is synthetic monitoring explains the concept from the ground up; this page is about how it runs on your Shopify store.

Each run drives an automated browser through the configured journey and asserts the outcome at each step:

The run ends at the checkout page. It does not place an order, and it does not verify that a payment can be completed.

On a confirmed failure, Revenue Shield stores a video recording of the run, a Playwright trace and screenshots, and names the step where the run stopped. Your team reviews what the browser actually did rather than guessing from a status change. Merchants are alerted by email, with SMS available on eligible plans and webhook alerts on the top tier.

Every run executes a desktop viewport and a mobile viewport in sequence, because some failures only appear at one size. These are responsive browser viewports, not real physical devices, so a run reflects how the store behaves at those viewport sizes in an automated browser — not a test on specific handsets.

Cadence and alert channels depend on your plan:

• Free — one purchase flow, checked 3 times daily (approximately every 8 hours), email and Slack alerts.
• Starter — up to three flows, checks as often as hourly, email and Slack alerts.
• Growth — up to three flows, hourly cadence, and adds SMS alerts plus CSV export.
• Top tier — broader coverage, cadence down to every 15 minutes, plus webhook alerts and AI console-log analysis.

Alerts follow a detected, confirmed failure: a first failure moves the test to an investigating state and an automatic retry runs a few minutes later, so the alert fires when the failure is confirmed rather than on a single raw failure. The gap between a break and your alert is the check interval plus the run duration plus that confirmation — it is scheduled, not instantaneous.

A passing run establishes that the flows, viewports and environment you configured worked at that time. It is deliberately scoped, and it is honest about what it does not cover:

• It covers the journeys you configured — not every product, variant, market or customer session.
• It stops before payment, so it does not verify that a card payment can be authorised or captured.
• It reflects automated browser viewports, not real physical devices.
• Alongside it, storefront script observations are clues for investigation, not proof of a cause.

Treat a passing run as evidence for what you tested, not a guarantee for the whole store.

Install the Revenue Shield app from the Shopify App Store, let it generate and validate your purchase-flow tests, review the flows, and start monitoring. There are no browser scripts to write by hand. From there, checkout monitoring focuses on reaching checkout, and the store monitoring overview compares this with availability checks and script monitoring.
