Entity Type Reference

Users can ask Alexa to search for video content by specifying characteristics of the content, such as a season and episode of a TV show, or a genre of movie. Alexa sends these characteristics, called entity types, to your skill in the entities array. This reference defines the entity types that Alexa might send to your skill.

Some entity types include external identifiers that provide additional information about the entity. The external identifier is a key-value map where the key defines the provider of the identifier. For example, IMDb is the provider of video content identifiers in the IMDb database.

Important: The Gracenote catalog is deprecated.
