Reference-Based Catalog Management

With the Reference-Based Catalog Management API, you can create a custom slot type that references an external data source to get the slot type values. This API allows you to create and maintain a catalog of slot type values independent of your Alexa skill.

As part of using the API, you provide the URL for your external data source, and the API returns a catalog identifier. In your custom slot type, you specify the catalog identifier so that the skill can get the slot type values from the external data source. For example, if you're building a recipe skill, instead of entering ingredients as slot type values in your Alexa skill, you specify the catalog identifier for your external data source that has the list of ingredients.

Process to use the Reference-Based Catalog Management API

Do the following steps to start using the Reference-Based Catalog Management API.

  1. Create a definition for your catalog.
  2. Create a catalog version using the catalog id from step 1.
  3. Track the status of the catalog version creation. The possible values are in progress, failed, or succeeded.
  4. Use the catalog ID and version in the interaction model as shown in the following example.
