Hello @GeethaNagarajan ,
This is not an issue with your flow — it’s happening because of CORS (a browser security rule). By default, browsers block requests to APIs that don’t allow your app’s domain.

For learning and testing, you can install a CORS extension in your browser. The extension adds a header called Access-Control-Allow-Origin which tells the browser to allow the request. That’s why the extension is needed — otherwise, the browser will block it.

Later, when you work on real projects, this will usually be fixed from the backend side, so you won’t need the extension
