A moderator will be better placed to answer. But imo, yes, you can leave it here and update with important announcements and you follow discussions easier on the other one. The service fits into both boards so it's not out of place to have them there, just do not overdo it with multiple other threads which could clog up the board.
Yes, of course – that's what we wanted – to publish only important news about our API here.
Let's wait and see what the moderator has to say.
Thank you again for your attention and recommendations.
