For iOS, If I send a deep link to another user for a particular iOS application, how can I get the uniqueness of it, like unique applicationId, deviceId, to get the particular item or content at the position in that particular application.

I found some key things, that can i use, but still i confused, as I want to extract some unique fields like applicationId (for particular app), userId (who send the link), deviceId (for which device the app is downloaded).

• IMEI
• IDFA
• IDFV
• Bluetooth Address
• WLAN MAC Address

Facing problem in Universal Link, when user clicks on that link, then user reached to the home page of mobile application, where application lies, but it doesn’t opening the app.
