We announced the upcoming end-of-support for AWS SDK for JavaScript v2.
We recommend that you migrate to AWS SDK for JavaScript v3. For dates, additional details, and information on how to migrate, please refer to the linked announcement.

Class: AWS.PersonalizeRuntime

Inherits:
AWS.Service show all
Identifier:
personalizeruntime
API Version:
2018-05-22
Defined in:
(unknown)

Overview

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

Service Description

Sending a Request Using PersonalizeRuntime

var personalizeruntime = new AWS.PersonalizeRuntime();
personalizeruntime.getActionRecommendations(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 PersonalizeRuntime object uses this specific API, you can construct the object by passing the apiVersion option to the constructor:

var personalizeruntime = new AWS.PersonalizeRuntime({apiVersion: '2018-05-22'});

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

AWS.config.apiVersions = {
  personalizeruntime: '2018-05-22',
  // other service API versions
};

var personalizeruntime = new AWS.PersonalizeRuntime();

Constructing a PersonalizeRuntime object

var personalizeruntime = new AWS.PersonalizeRuntime({apiVersion: '2018-05-22'});

Options Hash (options):

  • params (map)

    An optional map of parameters to bind to every request sent by this service object. For more information on bound parameters, see "Working with Services" in the Getting Started Guide.

  • endpoint (String|AWS.Endpoint)

    The endpoint URI to send requests to. The default endpoint is built from the configured region. The endpoint should be a string like 'https://{service}.{region}.amazonaws.com' or an Endpoint object.

  • accessKeyId (String)

    your AWS access key ID.

  • secretAccessKey (String)

    your AWS secret access key.

  • sessionToken (AWS.Credentials)

    the optional AWS session token to sign requests with.

  • credentials (AWS.Credentials)

    the AWS credentials to sign requests with. You can either specify this object, or specify the accessKeyId and secretAccessKey options directly.

  • credentialProvider (AWS.CredentialProviderChain)

    the provider chain used to resolve credentials if no static credentials property is set.

  • region (String)

    the region to send service requests to. See AWS.PersonalizeRuntime.region for more information.

    the maximum amount of redirects to follow with a request. See AWS.PersonalizeRuntime.maxRedirects for more information.

  • sslEnabled (Boolean)

    whether to enable SSL for requests.

  • paramValidation (Boolean|map)

    whether input parameters should be validated against the operation description before sending the request. Defaults to true. Pass a map to enable any of the following specific validation features:

    • min [Boolean] — Validates that a value meets the min constraint. This is enabled by default when paramValidation is set to true.
    • max [Boolean] — Validates that a value meets the max constraint.
    • pattern [Boolean] — Validates that a string value matches a regular expression.
    • enum [Boolean] — Validates that a string value matches one of the allowable enum values.
  • computeChecksums (Boolean)

    whether to compute checksums for payload bodies when the service accepts it (currently supported in S3 only)

    whether types are converted when parsing response data. Currently only supported for JSON based services. Turning this off may improve performance on large response payloads. Defaults to true.

  • correctClockSkew (Boolean)

    whether to apply a clock skew correction and retry requests that fail because of an skewed client clock. Defaults to false.

  • s3ForcePathStyle (Boolean)

    whether to force path style URLs for S3 objects.

    • base [Integer] — The base number of milliseconds to use in the exponential backoff for operation retries. Defaults to 100 ms for all services except DynamoDB, where it defaults to 50ms.
    • customBackoff [function] — A custom function that accepts a retry count and error and returns the amount of time to delay in milliseconds. If the result is a non-zero negative value, no further retry attempts will be made. The base option will be ignored if this option is supplied. The function is only called for retryable errors.

  • systemClockOffset (Number)

    an offset value in milliseconds to apply to all signing times. Use this to compensate for clock skew when your system may be out of sync with the service time. Note that this configuration option can only be applied to the global AWS.config object and cannot be overridden in service-specific configuration. Defaults to 0 milliseconds.

Method Details

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

Returns a list of recommended actions in sorted in descending order by prediction score. Use the GetActionRecommendations API if you have a custom campaign that deploys a solution version trained with a PERSONALIZED_ACTIONS recipe.

For more information about PERSONALIZED_ACTIONS recipes, see PERSONALIZED_ACTIONS recipes. For more information about getting action recommendations, see Getting action recommendations.

Service Reference:

Examples:

Calling the getActionRecommendations operation

var params = {
  campaignArn: 'STRING_VALUE',
  filterArn: 'STRING_VALUE',
  filterValues: {
    '<FilterAttributeName>': 'STRING_VALUE',
    /* '<FilterAttributeName>': ... */
  },
  numResults: 'NUMBER_VALUE',
  userId: 'STRING_VALUE'
};
personalizeruntime.getActionRecommendations(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {})
    • campaignArn — (String)

      The Amazon Resource Name (ARN) of the campaign to use for getting action recommendations. This campaign must deploy a solution version trained with a PERSONALIZED_ACTIONS recipe.

    • userId — (String)

      The user ID of the user to provide action recommendations for.

    • numResults — (Integer)

      The number of results to return. The default is 5. The maximum is 100.

    • filterArn — (String)

      The ARN of the filter to apply to the returned recommendations. For more information, see Filtering Recommendations.

      When using this parameter, be sure the filter resource is ACTIVE.

    • filterValues — (map<String>)

      The values to use when filtering recommendations. For each placeholder parameter in your filter expression, provide the parameter name (in matching case) as a key and the filter value(s) as the corresponding value. Separate multiple values for one parameter with a comma.

      For filter expressions that use an INCLUDE element to include actions, you must provide values for all parameters that are defined in the expression. For filters with expressions that use an EXCLUDE element to exclude actions, you can omit the filter-values. In this case, Amazon Personalize doesn't use that portion of the expression to filter recommendations.

      For more information, see Filtering recommendations and user segments.
