Let’s begin and discover the full power of FCM and AWS SNS connection!

Part 1 - Setting Up Firebase Cloud Messaging

To connect Firebase Cloud Messaging (FCM) with AWS Simple Notification Service (SNS), we need to set up FCM in our Firebase project first. Let’s follow these steps to configure FCM:

  1. Create a Firebase Project:

    • We go to the Firebase Console.
    • Click on “Add project” and fill in the project details.
    • Then click “Create project”.

  2. Add an App to Your Project:

    • After we create the project, we click on “Add app” and choose our platform (iOS, Android, or Web).
    • We follow the instructions to register our app and download the google-services.json (for Android) or GoogleService-Info.plist (for iOS).

  3. Enable FCM:

    • In the Firebase Console, we go to “Cloud Messaging” under “Project settings”.
    • We copy the Server key and Sender ID. We need these for AWS SNS integration.

  4. Integrate FCM SDK:

    • For Android, we add this line to our build.gradle file:

      implementation 'com.google.firebase:firebase-messaging:23.0.0'

    • For iOS, we use CocoaPods to add the Firebase Messaging SDK:

      pod 'Firebase/Messaging'

  5. Configure Your App:

    • For Android, we start Firebase in the onCreate method of our main activity:

      FirebaseApp.initializeApp(this);

    • For iOS, we set up Firebase in our AppDelegate.swift:

      import Firebase
FirebaseApp.configure()

  6. Test FCM Setup:

    • We use the Firebase Console to send a test message. This helps to check if our app is ready to receive messages.

By doing these steps, we will have set up Firebase Cloud Messaging. Now we can continue with the integration to AWS SNS. For more help on fixing FCM notifications, we can look at Monitoring and Debugging Notifications.

Part 2 - Creating an AWS SNS Topic

To connect Firebase Cloud Messaging (FCM) with AWS Simple Notification Service (SNS), we need to make an SNS topic first. Let us follow these steps to set up our AWS SNS topic:

  1. Log into the AWS Management Console.

  2. Go to the SNS Dashboard.

  3. Create a Topic:

    • Click on Topics on the left side.
    • Click on the Create topic button.

  4. Configure Topic Settings:

    • Choose Standard or FIFO (First-In-First-Out) depending on what we need.
    • Give a name for our topic (for example, MyFCMTopic).
    • If you want, you can also add a Display Name for SMS notifications.
    • Click Create topic.

  5. Note the Topic ARN:

    • After we create the topic, we should copy the Topic ARN (Amazon Resource Name) shown on the topic details page. It looks like this:

      arn:aws:sns:REGION:ACCOUNT_ID:MyFCMTopic

  6. Set Access Policies (this is optional but good to do):

    • We might want to set access policies. This helps specific AWS services or IAM roles to send messages to our topic.

  7. Save the Topic ARN for later when we set up FCM with AWS SNS.

This AWS SNS topic will help us send notifications to FCM. This way, our application can get push notifications. For more details, check the AWS SNS documentation.

Part 3 - Configuring Firebase Credentials in AWS SNS

We need to set up Firebase Cloud Messaging (FCM) with AWS Simple Notification Service (SNS). To do this, we must configure Firebase credentials in AWS SNS. Here are the steps we should follow:

  1. Get Server Key from Firebase Console:

    • Go to the Firebase Console.
    • Choose your project and go to Project settings.
    • In the Cloud Messaging tab, copy the Server Key.

  2. Make a Platform Application in AWS SNS:

    • Open the AWS Management Console and go to the SNS Dashboard.
    • Click on Mobile and then Push notifications.
    • Click Create platform application.
    • Fill in these details:
      • Platform: Choose Firebase Cloud Messaging.
      • Application name: Give your application a name.
      • Credential: Paste the Server Key from Firebase.
    • Click Create platform application.

  3. Set Up the Application:

    • After we create the application, write down the Platform Application ARN.
    • We will use this ARN in the next steps to send messages using SNS.

  4. Setup IAM Permissions:

    • We need to make sure that the IAM roles for our AWS services have permissions for SNS actions. If needed, attach this policy:
    {
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": ["sns:Publish", "sns:CreatePlatformEndpoint"],
      "Resource": "*"
    }
  ]
}

  5. Test Your Setup:

    • Use the AWS SNS Console to send a test message to our platform application.
    • Check if the message arrives on your device.

For more info on AWS SNS and FCM integration, we can read this article on how to send notifications via AWS SNS.

Let’s follow these steps carefully to make sure we set up Firebase credentials in AWS SNS correctly.

Part 4 - Sending Test Notifications via AWS SNS

To send test notifications using AWS Simple Notification Service (SNS) with Firebase Cloud Messaging (FCM), we can follow these simple steps.

  1. Go to SNS Console: We need to visit the AWS SNS Console.

  2. Choose the Topic: We will select the SNS topic we made for FCM integration.

  3. Send a Message: Click on the “Publish message” button.

  4. Set Up the Message:

    • Message Type: We choose “Text” or “JSON” based on what we need.
    • Message Body: If we use JSON, we can write the message like this:
    {
  "notification": {
    "title": "Test Notification",
    "body": "This is a test notification from AWS SNS to FCM"
  }
}

  5. Select the FCM Endpoint: In the “Select endpoints” area, we pick the FCM endpoint that matches the device or app we want to send the notification to.

  6. Send the Message: We click on the “Publish” button to send the notification.

  7. Check Delivery: We should look at the device or app to see if the notification arrived. If it did not arrive, we need to check our FCM settings in AWS SNS according to this guide.

We must ensure our IAM permissions are set right so the SNS service can send notifications to FCM. If we have problems, we can check the SNS logs for any mistakes or delivery issues.

Part 5 - Integrating FCM with AWS SNS Using SDK

To connect Firebase Cloud Messaging (FCM) with Amazon Web Services Simple Notification Service (AWS SNS) using the SDK, we can follow these easy steps.

  1. Set Up AWS SDK: First, we need the AWS SDK for the programming language we are using. For example, if we use Node.js, we can install the SDK by running:

    npm install aws-sdk

  2. Configure AWS Credentials: Next, we have to set up our AWS credentials. We can do this by creating a file at ~/.aws/credentials:

    [default]
aws_access_key_id = YOUR_AWS_ACCESS_KEY
aws_secret_access_key = YOUR_AWS_SECRET_KEY

  3. Initialize AWS SNS: Now, we will use the SDK to start the AWS SNS client. Here is a simple example for Node.js:

    const AWS = require("aws-sdk");
AWS.config.update({ region: "YOUR_AWS_REGION" });
const sns = new AWS.SNS();

  4. Prepare FCM Message: We need to format the message we want to send through FCM. We should include the Message and TargetArn (the ARN of the platform endpoint we created before):

    const params = {
  Message: JSON.stringify({
    default: "Default message",
    GCM: JSON.stringify({
      notification: {
        title: "Hello FCM",
        body: "This is a notification message!",
      },
    }),
  }),
  TargetArn: "YOUR_PLATFORM_ENDPOINT_ARN",
};

  5. Send SNS Notification: We can now call the publish method of the SNS client to send the notification:

    sns.publish(params, (err, data) => {
  if (err) {
    console.error("Error sending notification", err);
  } else {
    console.log("Notification sent successfully", data);
  }
});

  6. Testing: After we write the code above, we should run our script. We can check the FCM console or our app to see if we received the notification.

Don’t forget to replace the placeholders like YOUR_AWS_ACCESS_KEY, YOUR_AWS_SECRET_KEY, YOUR_AWS_REGION, and YOUR_PLATFORM_ENDPOINT_ARN with your real credentials and endpoint info.

For more info about AWS SDK integration, we can look at the AWS SDK Documentation. This integration helps us use the features of both FCM and AWS SNS together.

Part 6 - Monitoring and Debugging Notifications

To monitor and debug notifications from Firebase Cloud Messaging (FCM) through Amazon Simple Notification Service (SNS), we can use AWS CloudWatch and the Firebase console. Here are the steps:

  1. Enable CloudWatch Logging:

    • First, we go to the AWS Management Console and find the CloudWatch service.
    • Next, we create a new log group for our SNS notifications.
    • In the SNS console, we pick our topic and click on “Edit”.
    • Then, we find the “Delivery status logging” section and turn on logging for both successful deliveries and failures.
    • Finally, we select the log group we made earlier.

  2. Set Up Metrics and Alarms:

    • Now, we go to the CloudWatch console and look for “Metrics”.
    • We search for SNS metrics like NumberOfNotificationsDelivered and NumberOfNotificationsFailed.
    • We can create alarms for these metrics. This helps us to get alerts if the delivery rate goes down.

  3. Using the Firebase Console:

    • We open the Firebase console and choose our project.
    • Then, we go to the “Cloud Messaging” section. Here we can see stats about message delivery. This includes how many messages we sent, received, and open rates.
    • If notifications are not received, we should check for errors in the Firebase console.

  4. Debugging Payloads:

    • We need to check that the payload structure is correct. This is a good example:
    {
  "to": "<DEVICE_TOKEN>",
  "notification": {
    "title": "Test Notification",
    "body": "This is a test notification."
  },
  "data": {
    "key1": "value1",
    "key2": "value2"
  }
}

  5. Check for Common Issues:

    • We must verify that the device tokens are valid and not expired.
    • We also have to make sure the FCM Server Key is set up right in AWS SNS.
    • We should look at the IAM permissions for the SNS role to make sure it has the right permissions to send notifications.

  6. Review Error Messages:

    • We check the CloudWatch logs for any error messages about SNS delivery problems.
    • We look for specific error codes like “NotRegistered” or “InvalidRegistration”. These can show us problems with device tokens.
