I am building a group IM app (like GroupMe), and I want to allow users to invite new users to the app by adding them to a group, so when the new user installs and opens the app, they are automatically added to the group.
I have most of this implemented, but I cannot figure out how to pass data to the installation so that I can add the new user to the group.
Is it possible to trigger a custom action upon installation?
Right now I'm texting invite URLs that forward the user to the App Store:
http://appstore.com/appname/appname
If I add parameters to the end of it, how do I retrieve them in the app code?
I have been researching but maybe I'm just looking for the wrong thing. I found "deep linking" frameworks like http://applinks.org/ but this doesn't seem to help with custom invites.
