PVR Firebase Notification

Introduction

Firebase Cloud Messaging (FCM) is a service provided by Google that enables you to send targeted and personalized messages to your app users. Firebase Push Notification is a feature of FCM that allows you to send notifications to your users, even when they are not actively using your app. In this tutorial, we will explore how to use Firebase Push Notification, also known as PVR (Push Visual Response) in Firebase.

Prerequisites

Before we start, make sure you have the following:

• A Firebase project set up in the Firebase console
• A mobile app (iOS or Android) that you want to send notifications to
• The Firebase SDK integrated into your app
• A basic understanding of programming and Firebase

What is PVR (Push Visual Response)?

PVR is a feature of Firebase Push Notification that allows you to send visually-rich notifications to your users. With PVR, you can send notifications with custom images, buttons, and even interactive elements like swipeable cards. PVR is designed to provide a more engaging and interactive notification experience for your users.

Setting up PVR

To set up PVR, you need to:

1. Enable FCM: Go to the Firebase console and navigate to the "Cloud Messaging" tab. Click on the "Get started" button to enable FCM.
2. Create a server key: In the FCM settings, click on the "Create a server key" button. This key will be used to authenticate your server-side requests to FCM.
3. Install the Firebase SDK: In your mobile app, install the Firebase SDK using Gradle (for Android) or CocoaPods (for iOS).
4. Configure the Firebase SDK: Initialize the Firebase SDK in your app and set up the FCM service.

Sending a Push Notification with PVR

To send a push notification with PVR, you need to:

1. Create a notification payload: Create a JSON payload that contains the notification details, such as the title, message, and PVR data.
2. Set up the PVR data: In the notification payload, set up the PVR data, including the image, buttons, and interactive elements.
3. Send the notification: Use the Firebase SDK to send the notification to your users.

PVR Data Structure

The PVR data structure is a JSON object that contains the following properties:

• image: The URL of the image to display in the notification
• buttons: An array of button objects, each containing the button text and URL
• swipeable_cards: An array of swipeable card objects, each containing the card title, text, and URL

Example PVR Data Structure

{
  "image": "https://example.com/notification-image.png",
  "buttons": [
    {
      "text": "Button 1",
      "url": "https://example.com/button-1-url"
    },
    {
      "text": "Button 2",
      "url": "https://example.com/button-2-url"
    }
  ],
  "swipeable_cards": [
    {
      "title": "Card 1",
      "text": "This is card 1",
      "url": "https://example.com/card-1-url"
    },
    {
      "title": "Card 2",
      "text": "This is card 2",
      "url": "https://example.com/card-2-url"
    }
  ]
}

Handling PVR Notifications in Your App

To handle PVR notifications in your app, you need to:

1. Implement the Firebase SDK: Initialize the Firebase SDK in your app and set up the FCM service.
2. Handle the notification: In your app, implement a notification handler that listens for incoming notifications. When a notification is received, parse the notification payload and display the PVR data.
3. Display the PVR data: Use the PVR data to display the notification content, including the image, buttons, and interactive elements.

Conclusion

In this tutorial, we explored how to use Firebase Push Notification, also known as PVR, to send visually-rich notifications to your users. We covered the setup process, the PVR data structure, and how to handle PVR notifications in your app. With PVR, you can provide a more engaging and interactive notification experience for your users, increasing engagement and retention.
