Does Pushwoosh retry a push that APNs rejects?

Question:

If a push is not delivered through APNs, will Pushwoosh retry sending it?

Answer:

It depends on the type of failure:

If APNs rejects the push itself (for example, an invalid/expired device token or a disallowed topic), Pushwoosh does not retry — the rejection reason is recorded as the final delivery status and the push is not resent.
If sending fails at the transport level (a network error or timeout while talking to the APNs gateway), Pushwoosh automatically requeues the message for redelivery until it succeeds or the message expires — this is not limited to a single extra attempt.
