Push Notifications Or Webhooks

Push notifications and Webhooks are both technologies used in the tech field to deliver real-time information to users or systems. They serve similar purposes but operate in different ways and are used in different contexts. While push notifications are particularly beneficial in scenarios where immediate user attention is required, such as in social media alerts, news updates, and promotional messages, webhooks are most applicable in situations that demand instant data transfer following specific events. 

About Push Notifications

These are messages that are pushed from server to device, typically to a user’s mobile device or desktop via a web browser. They are used to deliver various types of information such as news updates, social media alerts, or application-specific notifications like chat messages or transaction alerts. It relies on a publisher-subscriber model. The application backend (publisher) sends a message to a push notification service, which then delivers the notification to the user’s device (subscriber). For mobile devices, this service is often provided by the platform’s operating system (e.g., Apple’s APNs for iOS, Google’s FCM for Android). For web browsers, this involves using service workers and the Push API.

Just think about your mobile banking apps to verify your transfer for example, in other words, these are mobile app alerts, real-time news updates, email notifications, promotional messages, reminders, etc. It serves multiple purposes such as direct engagement with users, works even when the user is not actively using the app or website, and supports media content. On the other hand, it requires your permission and you can always enable or disable it. 

What is a Webhook?

These are HTTP callbacks, which are triggered by specific events in a web application or service. They are used for real-time notifications between web applications and external servers or services. When an event occurs, the source site makes an HTTP request to the URL configured for the webhook. It delivers data to other applications in real time, meaning that you get data immediately as it happens. You set up a webhook by providing a URL to the service that will receive the webhook data. When the specified event occurs, the source application makes an HTTP POST request to the provided URL, delivering the data payload. The best examples are real-time data synchronisation between applications like Slack.

Which One Is Better?

When it comes to initiation, push notifications are initiated by the server and sent to a user’s device, while webhooks are triggered by events and send data from one server to another. Meanwhile, if we examine the angle of direction push notifications are typically one-way, from server to client and webhooks are also one-way but from server to server or server to service. In other words, one is designed mainly for user engagement and information delivery and the other is used for server-side automation and integration between different services.

Conclusion

Both push notifications and webhooks play important roles within the tech field, making real-time communication easier but in different ways.

The choice between push notifications and webhooks is based on the specific requirements of the task at hand. For direct user engagement and communication, push notifications are the clear choice. But for backend automation and real-time data exchange between services, webhooks provide a powerful and flexible solution. Understanding the benefits and optimal use of each technology allows developers and businesses to help them create smooth a user experience.
