recommendationsPerMessage property
The number of recommended items to retrieve from the model for each endpoint or user, depending on the value for the RecommendationProviderIdType property. This number determines how many recommended items are available for use in message variables. The minimum value is 1. The maximum value is 5. The default value is 5.
To use multiple recommended items and custom attributes with message variables, you have to use an AWS Lambda function (RecommendationTransformerUri) to perform additional processing of recommendation data.
