Advanced Push Campaign Settings
This reference article covers several advanced Push campaign setting such as Alert Options, Flags, Sounds, Expiry and more.
When creating push engagement, on the “Compose” step, you can select the “gear” icon to view the Advanced Settings available.
By clicking the checkbox here, you will notice a dropdown of key values available for adjusting how the notification will appear on devices.
Adding Content-Available Flag
content-available flag instructs devices to download new content in the background. Most commonly, this can be checked on should you be interested in sending silent notifications.
Adding Mutable-Content Flag
mutable-content flag enables advanced receiver customizations in iOS 10+ devices. This flag will automatically be sent when composing a rich notification, regardless of the value of this checkbox.
Here you can enter a path to a sound file in your app bundle to specify a sound to be played when the push message is received. If the specified sound file does not exist or should the keyword ‘default’ be entered, Braze will use the default device alert sound.
Specify a Collapse ID to coalesce similar notifications. If you send multiple notifications with the same Collapse ID, the device will only show the most recently received notification. For more information please find Apple’s documentation here.
Clicking the checkbox here will offer the option to set an expiration time for your message. Should a user’s device lose connectivity, Braze will continue to try and send the message until the specified time. If this is not set, the platform will default to an expiration of 30 days. Please note that push notifications that expire before delivery are not considered as failed and will not be recorded as a bounce.
