--- 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 --- # Monitoring for stores, aimed at the failures that cost money quietly 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 the DMARC record was edited. Every one of those returns a 200 to an uptime check. They are separate monitor types here. [Start free](/auth/signup)[See pricing](/pricing) ## 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) ## 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, from 20 locations, with per-region verdicts 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 or domain 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 alerts that fire on agreement between them rather than 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. - [Global monitoring locations](/monitoring) ## Where we are not the right answer - No scripted checkout walkthrough yet: we can verify every endpoint the checkout calls, but not a browser clicking through it. - 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? Not as a browser journey. You can monitor every API the checkout depends on, with assertions on what each returns, which catches most breakages — but a scripted click-through is a gap we are honest about. 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.
