# Requeue failed push notification messages

# Requeue failed push notification messages {#ariaid-title1}

Push notification delivery might fail for various reasons. You can view which
messages failed and requeue them to be sent out if necessary.

## Before you begin

Role required: admin

## About this task

Note:  
There is no way for the instance to guarantee or confirm push message delivery. For more information on how Apple handles push notifications, see the [Local and Remote Notification Programming
Guide](https://developer.apple.com/library/content/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/APNSOverview.html#/apple_ref/doc/uid/TP40008194-CH8-SW1) for Apple developers.

Messages can also fail to send for several reasons, such as a large message queue or
other issue with the instance. You can use a [system property](https://servicenow-prod.fluidtopics.net/he7WcMntJ0AxCKKG~Ginbw "Push notifications provides several properties to customize the setup.") to control how long the instance queues a push
notification after it is triggered.  
Push notification message payload size is limited by provider:

* Apple iOS: 2,048 bytes
* Google: 4,096 bytes

{#t_HandlingFailedPushMessages__ul_f3j_gcn_ss}Your instance does not send push messages that exceed this limitation. System logs save any failed messages. For details on Apple payload limitations, see the [Local and Remote Notification Programming
Guide](https://developer.apple.com/library/content/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/APNSOverview.html#/apple_ref/doc/uid/TP40008194-CH8-SW1) for Apple developers.

## Procedure

1. Navigate to AllSystem LogsPush Notifications.  
   By default, the messages that were created today appear. You can change the filter if necessary. The Type column can have these values:
   * failure: The message could not be sent.
   * pending: The message is queued for processing.
   * success: The message was successfully sent, although not necessarily received by the mobile device.
   {#t_HandlingFailedPushMessages__ul_dw2_g55_yhb}
2. Put any failed messages back into the queue to be resent by selecting the check boxes next to the failed messages, and then selecting Re-queue failed push notifications from the choice list.
3. If some push notifications continue to fail, consider increasing the value in the glide.push.notification.ttl_seconds property.  
   See [Push notification properties](https://servicenow-prod.fluidtopics.net/he7WcMntJ0AxCKKG~Ginbw "Push notifications provides several properties to customize the setup.") for more information.
