FB APP：允许Inf邀请使用fb用户的非应用

Question

I'm stuck with this 'big picture' problem:

In a fb-integrated web app I'm making, users can create little groups consisting of a couple of friends. They can invite a friend by sending a link (url).

Users should be able to invite every friend they have. In fact, there are 2 types of friends:

• The ones who also use the app
• The ones who don't use the app (yet)

I'm having a hard time figuring out a way to invite the latter ( the group of non-app using friends)

First of all, the fb graph api doesn't give acces to non-app using friends . By labeling my app as a 'game', and by setting up the canvas, I can however get the 'invitable friends', ie the friends who don't play the game yet

But a problem remains: I can't send a private message to an invitable friend, as I don't have their user id ( only a token to perform a game invite)

By sending a game invite , An invited user would simply be redirected to the fb canvas app , without entering the right group

I could use the fb share dialogbox , but then users have select the friends using the fb dialogbox ui, which strongly interferes with my mobile app's flow.

I hope you're getting to understand my problem. I'm interested in hearing your thoughts about this.

Answer 1

Just recently I had the same issue with the Graph API. I also wanted to particularly address non-app using friends to invite them to my iOS app. It's not a canvas app, so I didn't have access to the invitable friend API and also found that this is not a trivial issue.

anyway, if you're only interested in sending a message, i guess this is possible. this just wouldn't be an actual invite to the app, but rather really just a regular facebook message . do you need more info?
