Transaction Monitoring
Your transactions fail silently. Know when they break.
Signups, logins, checkouts, and bookings depend on dozens of scripts and assets. When one fails, the transaction breaks -- but the page still loads fine. Sitewatch monitors the dependencies that revenue-critical flows rely on, so you catch the #1 cause of broken transactions: missing or broken scripts and assets.
- Catch checkout failures from broken payment scripts and missing JS bundles
- Detect signup and login breakage before users start complaining
- Get alerted with the exact script, status code, and affected page

Revenue at stake
Every broken flow is lost revenue
Checkout failures
A broken Stripe script or missing checkout bundle means zero completed purchases. Your product pages load fine, but the money stops flowing.
Signup breakage
Authentication scripts, validation libraries, and form handlers can all fail independently. Your signup page renders, but new users cannot create accounts.
Login failures
When SSO scripts, auth providers, or session handlers break, existing users get locked out. Support tickets pile up while you hunt for the cause.
Search that returns nothing
Autocomplete scripts, search index connectors, and filter components can 404 after a deploy. Users see an empty search bar and leave.
Booking flows that stall
Calendar widgets, availability checkers, and reservation scripts are complex dependency chains. One missing asset and the entire booking flow dies.
Lead-gen forms that ghost
Contact forms, demo requests, and quote builders depend on scripts your uptime tool never checks. Visitors fill them out, hit submit, and nothing happens.

Silent failure modes
How transaction flows break silently
Payment & checkout
- Stripe, PayPal, or Braintree scripts returning 404 after CDN changes
- Checkout JavaScript bundles served with wrong MIME type
- Cart and payment form CSS missing, rendering unusable inputs
- Price calculation scripts failing to load from third-party CDNs
Authentication & signup
- Auth0, Firebase Auth, or SSO provider scripts returning errors
- reCAPTCHA and bot-protection scripts going down
- Signup form validation libraries failing to load
- OAuth and social login widget scripts blocked by CORS or redirects
Search & navigation
- Algolia, Elasticsearch, or custom search scripts returning errors
- Autocomplete and filter component bundles missing after deploys
- Navigation menu scripts 404-ing, breaking site-wide UX
- Booking widget and calendar component dependencies failing
How it works
How Sitewatch monitors transaction dependencies
Add your transaction pages
Point Sitewatch at your checkout, signup, login, and search pages. Each URL is fetched and parsed to discover every script and asset the page depends on.
Verify every dependency
Every JavaScript bundle, stylesheet, and third-party script gets a HEAD request. Sitewatch validates HTTP status codes and MIME types to confirm each dependency loads correctly.
Confirm with retries
Detected failures go through 2-of-3 retry confirmation. Only persistent issues create an incident -- transient CDN hiccups don't trigger false alerts.
Alert with evidence
When a transaction-critical script fails, you get a Slack or email alert with the exact asset URL, HTTP status, MIME type, and which transaction page is affected.

The monitoring gap
Uptime tools vs. transaction monitoring
| Feature | Uptime tools | Sitewatch |
|---|---|---|
| Checkout scripts | Not checked | Every payment script verified for status + MIME type |
| Auth dependencies | Invisible | Login, SSO, and signup scripts validated each check |
| Search components | Outside scope | Search and filter scripts verified per page |
| Third-party providers | Ignored | Stripe, Auth0, reCAPTCHA, Algolia -- all checked |
| Post-deploy verification | Ping says 200 OK | Full dependency scan after every deploy |
| Failure evidence | Up or down | Exact URL, HTTP status, MIME type, affected page |

FAQ
Frequently asked questions
No. Sitewatch monitors the scripts and assets that transaction flows depend on -- payment processors, auth libraries, form handlers, and search components. It does not click through multi-step flows in a browser. Instead, it catches the #1 cause of broken transactions: missing or broken scripts and assets that silently disable the flow while the page still loads.
Sitewatch checks the dependencies behind checkout, signup, login, search, booking, and lead-gen flows. Any page you add gets a full dependency scan: every JavaScript bundle, stylesheet, and third-party script is verified for correct HTTP status and MIME type.
Uptime tools check if your server returns a 200 response. Your checkout page can return 200 while the Stripe script is 404-ing and no one can pay. Transaction monitoring verifies the specific scripts and assets that each flow depends on -- the layer between "site is up" and "users can actually transact."
Sitewatch checks as frequently as every 5 minutes on Pro, or every 30 minutes on Free. You can also trigger on-demand checks from the dashboard or via deploy hooks. When a confirmed failure is detected, alerts go to your configured channels immediately with the exact script URL, status code, and affected page.
Yes. Sitewatch checks every script referenced in your page HTML, including third-party providers like Stripe, PayPal, Auth0, Firebase, reCAPTCHA, and Algolia. If any of them return errors, wrong MIME types, or redirect to error pages, you get an alert with full details.
