What is the interval that push notifications are resent upon failure?
Validic will send a push notification a maximum of three times within 10 minutes. If the first attempt to send a push notification fails, the second attempt will be scheduled a few minutes later. This means that Validic did not receive an HTTP status code of 204 within 3 seconds. The same will happen if the second attempt fails. If the third attempt fails Validic will not queue that push notification to be sent again.
If for some reason the push notification handler configured to receive Validic's notifications was unavailable for a period long enough to miss the original notification and the two retries, the Validic support team can assist with getting those notifications resent if necessary upon request.
