iOS 16.4 integration with Ocamba

Apple has released iOS 16.4, with many new features and improvements. One of the most notable changes is the addition of web push notifications, which will undoubtedly significantly impact the industry.

This is a game-changer for businesses and marketers, as it removes the need for users to go through the hassle of downloading an app to stay up to date with their favorite websites.

So, how will this release change the industry of push notifications? This article will examine the new web push notifications feature and how it will impact businesses and users.

What are Web push notifications

Web push notifications are messages sent to a user's device through a web browser. Unlike traditional push notifications, sent through a mobile app, web push notifications can be sent directly from a website to a user's device, even when the user is not on the website.

Until now, push notifications were only available through native apps. However, with the introduction of web push notifications on iOS 16.4, websites can directly send push notifications to iOS devices without requiring users to install a dedicated app.

The importance of Web push notifications

Web push notifications are a powerful tool for businesses and marketers as they provide an additional channel for communicating with their audience. These notifications can inform users about new content, updates, promotions, etc. Web push notifications are becoming increasingly popular as they offer a way for websites to engage with users and drive traffic back to their sites.

How will this release impact the push notifications software industry?

For push notification software companies, iOS 16.4 is a significant development that demands attention. The latest update from Apple brings a range of new features that will significantly impact the industry.

One of the most noteworthy changes in iOS 16.4 is the ability to send web push notifications to users. With over 1 billion active devices (27.6% market share in the global smartphone industry), this opens many new opportunities for marketers and companies.

The enhanced privacy and security settings mean users have more control over which apps/sites can send notifications, requiring push notification software companies to ensure their messages are relevant, valuable, and personalized to avoid being blocked. As such, companies in the push notification industry need to adapt and innovate their services to meet these new challenges and stay competitive.

In addition, iOS 16.4 also introduces new emojis and innovative ways to edit content. This offers companies a unique opportunity to create more expressive and creative messages that engage their audience.

How to enable Web Push notifications on iOS 16.4 devices

If you're a website owner or marketer, you may wonder how to enable web push notifications on iOS 16.4. The good news is that it's relatively easy to get started.

The first step is ensuring your website is compatible. Most modern browsers support web push notifications, including Safari, on iOS devices.

Push API and Notifications API

To enable web push notifications on iOS 16.4, users need to use the Push API and Notifications API. The Push API is used to register a user for push notifications and receive the user's permission to send messages (Settings -> Safari -> Advanced -> Experimental Features -> Push API to click on the toggle button to enable it). The Notifications API creates and sends notifications to the user's device.

First, the user has to visit a desired webpage. Then, click on the share option and choose the "Add to home screen" option. Once this has been done, the user must click on the native-like app that will appear on the home screen. When the user opens the app, he must click somewhere on it for the push prompt to appear and to opt-in for push notifications.

Step 2: Link the manifest file (server-side)

Step 3: Enable experimental Push API

For web push to work in iOS and iPadOS, at the time of writing, it is necessary to enable the experimental feature Push API. This is done by setting the toggle button on the following path.

Settings → Safari → Advanced → Experimental Features → Push API

And set the toggle button to green color; this way, Push API is enabled.

Step 4: Add to the home screen

Unlike significant browsers like Chrome and Firefox, you cannot request push permission on Safari iOS/iPadOS unless your website has been added to the user’s home screen.

The Add to Homescreen feature lets users bookmark your website, adding your icon to their valuable home screen real estate.
