Hi @shabbir9,

1. Incorrect URL: Make sure that the URL you’re using in the src attribute of the iframe is correct. Double-check for typos or issues with the URL.
2. Authentication: If the URL requires authentication using JSON data, you’ll likely need to include the authentication data in your widget. You can’t include JSON data directly in an iframe source. Instead, you may need to use JavaScript to make an AJAX request to the authentication endpoint, receive a token or authentication key, and then include that in the URL of the iframe.
3. Cross-Origin Restrictions: Browsers have security restrictions that may prevent an iframe from accessing content on a different domain if the proper CORS (Cross-Origin Resource Sharing) headers are not set on the remote server. Ensure that the server hosting the content in the iframe allows requests from your domain.

Please mark it as solution proposed and helpful if it serves your purpose.

Thanks,

Anand
