Adding device tokens or registration IDs - Amazon Simple Notification Service
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Adding device tokens or registration IDs

When you first register an app and mobile device with a notification service, such as Apple Push Notification Service (APNs) and Firebase Cloud Messaging (FCM), device tokens or registration IDs are returned from the notification service. When you add the device tokens or registration IDs to Amazon SNS, they are used with the PlatformApplicationArn API to create an endpoint for the app and device. When Amazon SNS creates the endpoint, an EndpointArn is returned. The EndpointArn is how Amazon SNS knows which app and mobile device to send the notification message to.

You can add device tokens and registration IDs to Amazon SNS using the following methods:

  • Manually add a single token to Amazon using the Amazon Web Services Management Console

  • Upload several tokens using the CreatePlatformEndpoint API

  • Register tokens from devices that will install your apps in the future

To manually add a device token or registration ID

  1. Sign in to the Amazon SNS console.

  2. Choose Mobile, and then choose Push Notifications.

  3. In the Platform applications section, select your application and then choose Edit. If you haven't already created a platform application, create one now. For instructions on how to do this, see Creating a platform application.

  4. Choose Add Endpoints.

  5. In the Endpoint Token box, enter either the token ID or registration ID, depending on which notification service. For example, with ADM and FCM you enter the registration ID.

  6. (Optional) In the User Data box, enter arbitrary information to associate with the endpoint. Amazon SNS does not use this data. The data must be in UTF-8 format and less than 2KB.

  7. Finally, choose Add Endpoints.

    Now with the endpoint created, you can either send messages directly to a mobile device or send messages to mobile devices that are subscribed to a topic.

To upload several tokens using the CreatePlatformEndpoint API

The following steps show how to use the sample Java app (bulkupload package) provided by Amazon to upload several tokens (device tokens or registration IDs) to Amazon SNS. You can use this sample app to help you get started with uploading your existing tokens.

Note

The following steps use the Eclipse Java IDE. The steps assume you have installed the Amazon SDK for Java and you have the Amazon security credentials for your Amazon Web Services account. For more information, see Amazon SDK for Java. For more information about credentials, see How Do I Get Security Credentials? in the Amazon Web Services General Reference.

  1. Download and unzip the snsmobilepush.zip file.

  2. Create a new Java Project in Eclipse.

  3. Import the SNSSamples folder to the top-level directory of the newly created Java Project. In Eclipse, right-choose the name of the Java Project and then choose Import, expand General, choose File System, choose Next, browse to the SNSSamples folder, choose OK, and then choose Finish.

  4. Download a copy of the OpenCSV library and add it to the Build Path of the bulkupload package.

  5. Open the BulkUpload.properties file contained in the bulkupload package.

  6. Add the following to BulkUpload.properties:

    • The ApplicationArn to which you want to add endpoints.

    • The absolute path for the location of your CSV file containing the tokens.

    • The names for CSV files (such as goodTokens.csv and badTokens.csv) to be created for logging the tokens that Amazon SNS parses correctly and those that fail.

    • (Optional) The characters to specify the delimiter and quote in the CSV file containing the tokens.

    • (Optional) The number of threads to use to concurrently create endpoints. The default is 1 thread.

    Your completed BulkUpload.properties should look similar to the following:

    applicationarn:arn:aws-cn:sns:us-west-2:111122223333:app/FCM/fcmpushapp
csvfilename:C:\\mytokendirectory\\mytokens.csv
goodfilename:C:\\mylogfiles\\goodtokens.csv
badfilename:C:\\mylogfiles\\badtokens.csv
delimiterchar:' 
quotechar:"
numofthreads:5

  7. Run the BatchCreatePlatformEndpointSample.java application to upload the tokens to Amazon SNS.

    In this example, the endpoints that were created for the tokens that were uploaded successfully to Amazon SNS would be logged to goodTokens.csv, while the malformed tokens would be logged to badTokens.csv. In addition, you should see STD OUT logs written to the console of Eclipse, containing content similar to the following: 

    <1>[SUCCESS] The endpoint was created with Arn arn:aws-cn:sns:us-west-2:111122223333:app/FCM/fcmpushapp/165j2214-051z-3176-b586-138o3d420071
<2>[ERROR: MALFORMED CSV FILE] Null token found in /mytokendirectory/mytokens.csv
To register tokens from devices that will install your apps in the future

You can use one of the following two options:

  • Use the Amazon Cognito service: Your mobile app will need credentials to create endpoints associated with your Amazon SNS platform application. We recommend that you use temporary credentials that expire after a period of time. For most scenarios, we recommend that you use Amazon Cognito to create temporary security credentials. For more information, see the Amazon Cognito Developer Guide . If you would like to be notified when an app registers with Amazon SNS, you can register to receive an Amazon SNS event that will provide the new endpoint ARN. You can also use the ListEndpointByPlatformApplication API to obtain the full list of endpoints registered with Amazon SNS.

  • Use a proxy server: If your application infrastructure is already set up for your mobile apps to call in and register on each installation, you can continue to use this setup. Your server will act as a proxy and pass the device token to Amazon SNS mobile push notifications, along with any user data you would like to store. For this purpose, the proxy server will connect to Amazon SNS using your Amazon credentials and use the CreatePlatformEndpoint API call to upload the token information. The newly created endpoint Amazon Resource Name (ARN) will be returned, which your server can store for making subsequent publish calls to Amazon SNS.
