Notifications.sendSimple notifications are not displayed. CHADNT?

Question

Classmates

Hello!
I send notifications using an API call of the following form:

http://api.ok.ru/fb.do?application_key=<APP_KEY>&method=notifications.sendSimple&uid=<USER_ID>&text=Hello world!&mark=<SOME_MARK>&sig=<MD5_SIG>

In response I get True. However, the user does not see the notification, when I try to resend the notification, I get the following response:

{u'error_data': None, u'error_code': 11, u'error_msg': u'LIMIT_REACHED'}

Apparently the restriction for notifications.sendSimple works .
CHADNT? :)

Answer 1

For sendSimple / sendMass notifications, an additional filtering rule applies.
If a player is "addicted" to some games and actively plays them (for example, it can be determined by the presence of a link to at least one game in the list under the user's avatar on his page), then OK blocks notifications from other games for him.
He will see the sent notification (if its lifetime does not come out) if he stops actively playing other games.
Accordingly, the audience available for your notifications is players who are not actively playing other games at the moment, or who are addicted to your game. You can expand the audience beyond free users through other viral channels, for example, recommendations (suggest).

Answer 2

I would point out that suggest is currently the only working mechanism available to send notifications to users for new games. But it has a drawback - it's user-to-user notification, not server-side notifications.
