Quick facts
Detection methodology for Payment processors
Payment SDKs identify themselves through their script src URL (`js.stripe.com/v3/`, `www.paypal.com/sdk/js`, `cdn.adyen.com/`) and runtime globals (`Stripe`, `paypal`, `AdyenCheckout`). We surface the exact SDK version via the sourcemap when shipped — Stripe Elements 14.x vs 5.x, PayPal Checkout v5 vs v6 — which matters for security and compliance work much more than the categorical 'they use Stripe' answer.
How we detect Adyen
Each signal alone is rarely conclusive — Sourcemap Explorer cross-references all of them and weights by confidence. You can reproduce any of these checks yourself in Chrome DevTools.
Window-level global the technology installs on page. Reproducible by typing the path into the DevTools console.
window.adyen.encrypt.version = ^(.+)$
FAQ
How do I check if a website is using Adyen?
Open the page in Chrome, click the Sourcemap Explorer toolbar icon, and read the Stack tab. The popup matches Adyen's fingerprint signals (response headers, asset URL prefixes, runtime globals, sourcemap paths) and flags it whenever any combination is found. The same checks can be reproduced manually in DevTools — see the "How we detect" section above.
What Adyen version can Sourcemap Explorer detect?
Adyen ships as a hosted payment processors rather than a bundled npm package, so version-specific detection isn't always possible. Where the platform leaks a version in response headers (`X-Powered-By`, `Server`, generator meta tags) we surface it; otherwise we report presence only.
