url arguments (similar command line arguments for windows exe link)

hello,

is it possible to give the web app a parameter with it that i can read inside the power app?

start link like this

https://web.powerapps.com/apps/9ea70352-36ac-6468-c857-...?ticket=12345678&name=abc

so after start i can read this

ticket and name values?

Yes - you can use the Param function to retrieve the values that were passed as query string parameters to your app. In your case, the following expression when used in a formula would have the value "12345678":

Param("ticket")

Param is set when the app is started, as long as the app is running the Param will be set to that value.

I have a case where I would like to scan a QR coded url -> open item. (Using neoreader to scan the QR-code since the camera and barcodescanner of PowerApp does not work). If I scan a code and follow the link, PowerApps is launched and the app is launched with the item in the url. If I want to scan another url, I would have to close the app before I follow the link.

Is there a way to get the current passed variable from the url?
