+description: Prevent double-click / duplicate API calls from frontend UI
+alwaysApply: true
+---
+
+# Prevent duplicated API calls (frontend)
+
+When wiring UI actions (buttons, row actions, dialogs) to backend APIs, **always prevent double submission**. Relying on `setState` + `disabled` alone is not sufficient because rapid double-click can fire twice before React re-renders.
+
+- **Must**: add an **in-flight lock** (e.g. `useRef(false)`) and early-return if already running.
+- **Must**: keep the UI disabled/loading (`disabled={isLoading}`) for user feedback.
+- **Must**: clear the lock in `finally` so it always releases.
+- **Should**: if the same endpoint can be triggered from multiple places, consider a shared “single-flight” helper (dedupe by `method+url+body` key).
+
+Example pattern:
+
+```tsx
+const inFlightRef = useRef(false);
+const [isSaving, setIsSaving] = useState(false);
+
+const onSave = async () => {
+  if (inFlightRef.current) return;
+  inFlightRef.current = true;
+  setIsSaving(true);
+  try {
+    await doRequest();
+  } finally {
+    setIsSaving(false);
+    inFlightRef.current = false;
+  }
+};
+```
