--- title: Ecommerce Uptime & Checkout Monitoring description: Watch the parts of a store that lose money quietly: payment APIs, CDN caching, cart endpoints, certificate expiry and the mail that carries order confirmations. canonical: https://watchfor.io/for-ecommerce --- # Catch the store failures that cost money while every check stays green A store rarely goes down cleanly. It stays up while the payment API times out, while the CDN stops caching and every product image goes to origin, while order confirmations start landing in spam because someone edited the DMARC record. Every one of those returns a 200 to an ordinary uptime check. Here each one is its own monitor with its own alert — so you find out from us, not from your revenue report. [Start free](/auth/sign-up)[See pricing](/pricing) 9:41 9:41 ## The payment API, checked like an API An API monitor asserts on the JSON your payment provider returns, not only on the status code — so a gateway answering 200 with an error body is a failure rather than a green tick. The same applies to cart, inventory and shipping endpoints. - [API monitoring](/api-monitoring) ## Your checkout, clicked through around the clock A Playwright browser check opens the store in a real browser, searches, adds a product to the cart and walks to checkout, one timed step at a time. When a step breaks you get the step name, the error and a screenshot, and one flaky run never pages anyone: an incident needs a failed run and a failed confirmation re-run. - [Browser checks](/playwright-monitoring) ## The CDN bill nobody notices until it arrives When a deploy adds a Set-Cookie header and the CDN stops caching, nothing breaks — the site simply gets slower and every request goes to your origin. Cache hit ratio is a metric you can alert on here, checked from the regions your plan includes, and the free CDN Checker gives per-region verdicts from all 20 locations when only one part of the world is affected. - [CDN monitoring](/cdn-monitoring) ## Order confirmations that reach the inbox SPF, DKIM and DMARC are checked on a schedule rather than on the day a customer complains, and blacklist monitoring watches whether your sending IP has been listed. For a store, mail deliverability is part of the checkout flow even though it happens after it. - [Email deliverability](/email-monitoring) - [Blacklist monitoring](/blacklist-monitoring) ## Peak season, watched from where your customers are Twenty probe locations across seven regions, with every failure confirmed from several locations rather than alerting on a single failed check — so the traffic spike that makes one probe time out does not page anyone, and a genuine regional outage does. Your own servers can report from the inside as well — CPU, memory and disk through the open-source watchfor-agent — so a box running out of headroom on the busiest day of the year is an alert, not a surprise. - [Global monitoring locations](/monitoring) - [Server monitoring](/server-monitoring) ## Where we are not the right answer - No real user monitoring, so 'how fast was it for a customer in Berlin on 4G' is not a question we answer. - No fraud, inventory or business-metric monitoring — this is infrastructure, not commerce analytics. ## Questions people ask Can you test an actual checkout? Yes, with a Playwright browser check that adds a product to the cart and walks through checkout in a real browser. Stop before the payment unless your payment provider has a test mode. The Checkout template passes on a public demo shop as it is, so you can see it work before pointing it at your store. What should a store monitor first? The payment API with assertions, the cart or product API, the CDN cache hit ratio on your biggest asset, the certificate, and mail authentication. That combination covers the failures that stay invisible to a homepage check. Will it hold up on Black Friday? Checks run on their own schedule regardless of your traffic, and confirmation across locations stops a load spike from generating false alarms. What we cannot do is load-test you — that is a different kind of tool. ## Start with the thing you would hate to find out late 15 monitors free, commercial use allowed, no card required.
