If you aren't too comfortable with the API or Powershell try using a Powershell module.
I have access to the dashboard , I have given a url something like
This url I gave in the code it worked ,
If I need to get the data of some other page in dashboard which url i should give , the url which is on top of the dashboard ? Or something else
The base URL should always be the same, but the rest of the URL would change depending on the API Endpoint/Call used not the page you are browsing the dashboard UI
