Enable Push Synchronization

Amazon Cognito automatically tracks the association between identity and devices. Using the push sync feature, you can ensure that every instance of a given identity is notified when identity data changes. Push sync ensures that, whenever the sync store data changes for a particular identity, all devices associated with that identity receive a silent push notification informing them of the change.

You can enable Push Sync via the Amazon Cognito console. Choose Manage Federated Identities from the Amazon Cognito console:

  1. Click the name of the identity pool for which you want to enable Push Sync. The Dashboard page for your identity pool appears.

  2. In the top-right corner of the Dashboard page, click Edit identity pool. The Edit identity pool page appears.

  3. Scroll down and click Push synchronization to expand it.

  4. In the Service role dropdown menu, select the IAM role that grants Amazon Cognito permission to send an SNS notification. Click Create role to create or modify the roles associated with your identity pool in the AWS IAM console.

  5. Select a platform application, and then click Save Changes.
