I’ve now heard this twice while talking to QA engineers: “We don’t have an API.” Interesting.
So I ask:
-How does your web or mobile app talk to the backend?
-We use web services.
🙂
A web service is an API.
An API isn’t always a web service.
But a web service is always an API.
If your application loads data, saves forms, validates input, or shows a dashboard — it is sending HTTP requests. Those requests are your API surface, whether the team calls it that or not.
Open DevTools. Go to the Network tab. Refresh the page. There it is.
Most teams are already testing APIs — they just don’t realize it. And very often, testing those requests directly is faster, cleaner, and more powerful than clicking through the UI.
