Anyone knows if there has been any movement wrt an official Whatsapp server api? The reason I'm asking this that I work with communication/payment solutions for developing countries. Whatsapp usage is quite high in our user base but as long as there is no official api I figure I can wait. (As for why not Telegram: I like Telegram, I just got one of my extended family groups over there yesterday, the problem is that unlike Whatsapp it doesn't work on things like s40 and s60 phones which means it isn't an option everywhere.)
