Hello Soni,
I'm not sure I'm getting it right, but you can try to pass the parameter as an input in the url on the iframe. Then use that parameter however you see fit on your screen:


When declaring the iframe you can do something like :
<iframe src="https://yourenvironment.outsystemscloud.com/yourApplication/MyScreen?ListItemToChangeId=10" height="200" width="300"></iframe>
Best Regards,
Miguel Amado
