Overview

Constructs a service interface object. Each API operation is exposed as a function on service.

Service Description

Amazon Cognito Sync provides an AWS service and client library that enable cross-device syncing of application-related user data. High-level client libraries are available for both iOS and Android. You can use these libraries to persist data locally so that it's available even if the device is offline. Developer credentials don't need to be stored on the mobile device to access the service. You can use Amazon Cognito to obtain a normalized user ID and credentials. User data is persisted in a dataset that can store up to 1 MB of key-value pairs, and you can have up to 20 datasets per user identity.

With Amazon Cognito Sync, the data stored for each identity is accessible only to credentials assigned to that identity. In order to use the Cognito Sync service, you need to make API calls using credentials retrieved with Amazon Cognito Identity service.

If you want to use Cognito Sync in an Android or iOS application, you will probably want to make API calls via the AWS Mobile SDK. To learn more, see the Developer Guide for Android and the Developer Guide for iOS.

Sending a Request Using CognitoSync

var cognitosync = new AWS.CognitoSync();
cognitosync.bulkPublish(params, function (err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Locking the API Version

In order to ensure that the CognitoSync object uses this specific API, you can construct the object by passing the apiVersion option to the constructor:

var cognitosync = new AWS.CognitoSync({apiVersion: '2014-06-30'});

You can also set the API version globally in AWS.config.apiVersions using the cognitosync service identifier:

AWS.config.apiVersions = {
  cognitosync: '2014-06-30',
  // other service API versions
};

var cognitosync = new AWS.CognitoSync();

updateRecords(params = {}, callback) ⇒ AWS.Request

Posts updates to records and adds and deletes records for a dataset and user.

The sync count in the record patch is your last known sync count for that record. The server will reject an UpdateRecords request with a ResourceConflictException if you try to patch a record with a new value but a stale sync count.

For example, if the sync count on the server is 5 for a key called highScore and you try and submit a new highScore with sync count of 4, the request will be rejected. To obtain the current sync count for a record, call ListRecords. On a successful update of the record, the response returns the new sync count for that record. You should present that sync count the next time you try to update that same record. When the record does not exist, specify the sync count as 0.

This API can be called with temporary user credentials provided by Cognito Identity or with developer credentials.

      • SyncCount — required — (Integer) Last known server sync count for this record. Set to 0 if unknown.
      • DeviceLastModifiedDate — (Date) The last modified date of the client device.
    • SyncSessionToken — (String) The SyncSessionToken returned by a previous call to ListRecords for this dataset and identity.
    • ClientContext — (String) Intended to supply a device ID that will populate the lastModifiedBy field referenced in other methods. The ClientContext field is not yet implemented.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

        • Value — (String) The value for the record.
