Facebook send dialog to multiple friends using a recipients arrays

Question

The Facebook new Send Dialog lets people to send content to specific friends. But the API @ https://developers.facebook.com/docs/reference/dialogs/send/ said the parameter 'TO' means "A user ID or username".

I wonder is there a method to send message to multiple friends at one time. I tried to set the 'to' as a javascript arrays, but that does not work.

Answer 1

It seems that currently the sdk only takes the first element from the array that is passed to "To" parameter. This is really annoying and no formal explanation is given to this design decision. I'd wish it can take more than one uids or emails, group names etc.
