LG TV API HTTP POST to open a app on the TV

I want to open an app on my TV via an HTTP request but I can’t find the right URL to this I’ve tried the following URL:

Where can I find the right API URL can someone help me?

We are not sure exactly what your question is, but the webOS TV app is web-based. (See Web API and Web Engine.) It’s not much different from general web app development. If you can run your app on a web browser, you can also run it on the webOS TV. Thank you.
