All devices with Alexa built-in need to obtain a Login with Amazon (LWA) access token that is sent with each access request to the Alexa Voice Service (AVS). We provide different authorization options depending on the type of product you are building, making it easier for your customers to link their Amazon account with your product.
Code-Based Linking (CBL) is ideal for products with limited capabilities for customer input, such as smart TVs, wearables, and automotive accessories. Using CBL, the customer receives an alphanumeric code and a URL, usually displayed on the product screen that is accessed through a separate device to link their Amazon account with their device with Alexa built-in.
