OneSignal is a leading Push Communication API provider that enables developers to send notifications across various platforms, including mobile and web applications. It is widely used for its robust features, ease of integration, and ability to engage users effectively through timely notifications.
When using OneSignal, you might encounter an issue where notifications are not delivered with the expected urgency or are delayed. This is often due to the notification priority not being set, which can affect how notifications are handled by the device's operating system.
The root cause of this issue is typically the absence of a defined priority level in the notification payload. Notification priority determines how a notification is treated by the device's operating system, influencing its delivery speed and visibility.
In OneSignal, the priority of a notification can be set to influence its delivery behavior. For example, high-priority notifications are delivered immediately and can wake up a sleeping device, while low-priority notifications are delivered at a more convenient time.
To resolve this issue, you need to set the appropriate priority level in your notification payload. Follow these steps:
Log in to your OneSignal Dashboard and navigate to the project where you are experiencing the issue.
When creating or updating a notification, ensure that you include the priority field in the payload. Here is an example of how to set the priority:
{
"app_id": "YOUR_APP_ID",
"included_segments": ["All"],
"contents": {"en": "Your message here"},
"priority": 10
}
In this example, setting the priority to 10 indicates a high-priority notification.
After setting the priority, send a test notification to ensure it is delivered with the expected urgency. Monitor the delivery and adjust the priority as needed based on your requirements.
For more detailed information on setting notification priorities, refer to the OneSignal Documentation. You can also explore the OneSignal Blog for best practices and tips on optimizing your notification strategy.
