headers property

Map<String, String>? headers

HTTP request headers defined in Apple Push Notification Service.

Refer to APNs request headers for supported headers such as apns-expiration and apns-priority. The backend sets a default value for apns-expiration of 30 days and a default value for apns-priority of 10 if not explicitly set.
