Send push notifications

The Amazon Pinpoint 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 Amazon Pinpoint API by using an AWS SDK.

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

Note

When you send push notifications through the Firebase Cloud Messaging (FCM) service, use the service name GCM in your call to the Amazon Pinpoint API. The Google Cloud Messaging (GCM) service was discontinued by Google on April 10, 2018. However, the Amazon Pinpoint 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.

JavaScript (Node.js)

Use this example to send push notifications by using the AWS SDK for JavaScript in Node.js. This example assumes that you've already installed and configured the SDK for JavaScript in Node.js.

This example also assumes that you're using a shared credentials file to specify the Access Key and Secret Access Key for an existing user. For more information, see Setting credentials in the AWS SDK for JavaScript in Node.js Developer Guide.
