Hi, I'm building a very small Task Manager app, that allows users create different Task Lists, add tasks to those lists, and then invite people to join the Task List. I'd like to build in an invite system into the app, so that users can invite (email or SMS) their friends to join their Task List. I understand that the following would need to happen from the invite link / process when it is sent to the other user: A - download the app OR open the app if already installed B - signup to the app (if you are a new user) C - join the user to the Task List How can you complete this full process and keep A, B and C linked together. For example, if i send the invite to a friend who didn't have the app, and they end up being redirected to the App store to download the app... however can we link step C to the process? Thanks in advance to any help you may be able to give.
