Pretty simple...

For example, If I send 5 in a loop, will this trigger failure?

Just wondering if anyone with experience can ballpark this.

There's no specific limit in the docs (Communicating with APNs).

There are no caps or batch size limits for using APNs. The iOS 6.1 press release stated that APNs has sent over 4 trillion push notifications since it was established. It was announced at WWDC 2012 that APNs is sending 7 billion notifications daily.

If you're seeing throughput lower than 9,000 notifications per second, your server might benefit from improved error handling logic.

Error 429 indicates The server received too many requests for the same device token. If you are having issues, you might want to check Technical Note TN2265 - Troubleshooting Push Notifications
