Hey. We are developing an app where, with the users permission, we will send them silent push notifications multiple times an hour in order to trigger an upload. Is there any kind of limit or throttling that can happen?
Thanks, Red
Silent Push Notification Throttling?
There are all sorts of effective limits to the number of push events:
- If you send a push event before the previous one has been received by the device, the previous event is lost.
- iOS on the device does progressively greater throttling limiting the number of times the app will launch in the background.
- Apple reserves the right to throttle your push notifications server side.
So there are limits, but those limits end up being dynamic limits, and you need to ensure that it's okay if those messages are lost or ignored.
