We are looking at building a mobile app using the NING APIs. We are quite happy with what we can do in terms of functionality but there is one major missing capability or feature. Currently there doesn't seem to be any way of inviting contacts without logging in on the web. This means that customers have to go to a computer or log-in to the web via the mobile to be able to invite friends. Is there anyway of getting around this?
You are correct, there isn't a way to send invitations at this time using the Ning API. I've added a feature request to our internal tracking system for this feature.
One workaround is to use an outside email service and have the mobile application send the network's invitation link. That link only expires when you a generate a new link.
Good point, a personal invitation does result in you being friends once the invitation is accepted. I've passed along your needs.
