I have an app in TestFlight right now, and it's not ready to go public. I'm willing to add universal links to it, so I can invite my testers to test the app via a universal link which holds a few parameters.
The flow would be:
Generate a universal link with specific invitation params -> User taps on the link -> if TestFlight is not installed it will go download TestFlight -> then will go to download the app from TestFlight -> Then will run the app and pass the params
I have tried to validate the do-ability of this, but couldn't find any helping articles about it.
This is very doable.
External Testing
menu item in the left side menu and click the blue plus button to add a new group.Edit: Not sure exactly what you mean by a universal link which holds a few parameters
... so I hope this is still helpful
