Answer 1

Yes: you need use URL Schemes:

Essentially, one app registers the fact that it handles a particular URL prefix, and then to launch that app, you have to navigate to that URL.

You can pass parameters through this URL too

If you meant e-mail application, you can pass link according to mailto: scheme. The simplest example is @"mailto:someone@example.com".
