recommendationsDisplayName property
A custom display name for the standard endpoint or user attribute (RecommendationItems) that temporarily stores recommended items for each endpoint or user, depending on the value for the RecommendationProviderIdType property. This value is required if the configuration doesn't invoke an AWS Lambda function (RecommendationTransformerUri) to perform additional processing of recommendation data.
This name appears in the Attribute finder of the template editor on the Amazon Pinpoint console. The name can contain up to 25 characters. The characters can be letters, numbers, spaces, underscores (_), or hyphens (-). These restrictions don't apply to attribute values.
Implementation
