I have a problem with making apprequests for my website application. I can send invite with FB.ui "apprequests" method but this request is not shown on Facebook. It looks like it is blocked because it fires notification icon but in a second notification disappears.
I've found a workaround. I set application also as a canvas and make redirection from canvas to the website page. But I don't know if it will not be blocked or something in the future.
What is the recommended method to send an application requests from a website application?
