Sending a message - AWS End User Messaging Push

Sending a message

The AWS End User Messaging Push API can send transactional push notifications to specific device identifiers. This section contains complete code examples that you can use to send push notifications through the AWS End User Messaging Push API by using an AWS SDK.

You can use these examples to send push notifications through any push notification service that AWS End User Messaging Push supports. Currently, AWS End User Messaging Push supports the following channels: Firebase Cloud Messaging (FCM), Apple Push Notification Service (APNs), Baidu Cloud Push, and Amazon Device Messaging (ADM).

For more code examples on endpoints, segments, and channels see Code examples.

Note

When you send push notifications through the Firebase Cloud Messaging (FCM) service, use the service name GCM in your call to the AWS End User Messaging Push API. The Google Cloud Messaging (GCM) service was discontinued by Google on April 10, 2018. However, the AWS End User Messaging Push API uses the GCM service name for messages that it sends through the FCM service in order to maintain compatibility with API code that was written prior to the discontinuation of the GCM service.

GCM (AWS CLI)

The following example uses send-messages to send a GCM Push notification with the AWS CLI. Replace token with the unique token of the device and 611e3e3cdd47474c9c1399a50example with your application identifier.

if using ImageUrl field for GCM , pinpoint sends the field as data notification, with the key being pinpoint.notification.imageUrl, which can prevent the image from being rendered out of the box. Please use RawContent or add handling of the data keys such as integrating your app with AWS Amplify.

Safari (AWS CLI)

You can use AWS End User Messaging Push to send messages to macOS computers that use Apple's Safari web browser. To send a message to the Safari browser, you must specify the raw message content, and you must include a specific attribute in the message payload. You can do this by creating a push notification template with a raw message payload, or by specifying the raw message content directly in a campaign message, in the Amazon Pinpoint User Guide.

Note

This special attribute is required for sending to macOS laptop and desktop computers that use the Safari web browser. It isn't required for sending to iOS devices such as iPhones and iPads.

To send a message to Safari web browsers, you must specify the raw message payload. The raw message payload must include a url-args array within the aps object. The url-args array is required in order to send push notifications to the Safari web browser. However, it is acceptable for the array to contain a single, empty element.

The following example uses send-messages to send a notification to the Safari web browser with the AWS CLI. Replace token with the unique token of the device and 611e3e3cdd47474c9c1399a50example with your application identifier. 

aws pinpoint send-messages \ 
--application-id 611e3e3cdd47474c9c1399a50example \ 
--message-request 
'{
  "Addresses": {
    "token": 
    {
      "ChannelType":"APNS"
    }
  },
  "MessageConfiguration": {
    "APNSMessage": {
        "RawContent": 
          "{\"aps\": {\"alert\": { \"title\": \"Title of my message\", \"body\": \"This is a push notification for the Safari web browser.\"},\"content-available\": 1,\"url-args\": [\"\"]}}"
     }
  }
}'
\ --region us-east-1

For more information about Safari push notifications, see Configuring Safari Push Notifications on the Apple Developer website.

APNS (AWS CLI)

The following example uses send-messages to send a APNS Push notification with the AWS CLI. Replace token with the unique token of the device, 611e3e3cdd47474c9c1399a50example with your application identifier, and GAME_INVITATION with a unique identifier. 

aws pinpoint send-messages \
--application-id 611e3e3cdd47474c9c1399a50example \
--message-request 
'{
    "Addresses": {
     "token":
    {
      "ChannelType":"APNS"
    }
  },
  "MessageConfiguration": {
    "APNSMessage": {
      "RawContent": "{\"aps\" : {\"alert\" : {\"title\" : \"Game Request\",\"subtitle\" : \"Five Card Draw\",\"body\" : \"Bob wants to play poker\"},\"category\" : \"GAME_INVITATION\"},\"gameID\" : \"12345678\"}"
      }
