List Management REST API Reference

Note: Sign in to the developer console to build or publish your skill.

Use the List Management REST API to view, update, and traverse lists, including custom lists and default lists, such as the Alexa shopping and to-do lists. You can view and update lists and list items. Also, the API supports archived lists as read-only lists. You can read, but not modify or delete, an item on an archived list. For details about default lists, see Access the Alexa Shopping and To-Do Lists.

API endpoint

The endpoint of the List Management API is https://api.amazonalexa.com.

Authentication

For API requests from a skill session, include an authorization header whose value is the context.System.apiAccessToken retrieved from a request from Alexa, such as the LaunchRequest or IntentRequest. For more details, see Get access to Alexa lists.

For out-of-session API requests from a website or app, include a Login with Amazon (LWA) access token in the authorization header. For more details about how to obtain the access token, see Get a User-Specific Access Token for Out-of-Session Calls to Alexa.
