How an Alexa Skill Works

An Alexa skill has both an interaction model—or voice user interface—and application logic. When a customer speaks, Alexa processes the speech in the context of your interaction model to determine the customer request. Alexa then sends the request to your skill application logic, which acts on it. You provide your application logic as a back-end cloud service hosted by Alexa, AWS, or another server.

Multiple Skill Types

Choose your skill type based on what your skill will do. You can use purpose-built APIs and interaction models for common use cases like smart home, or use the custom skill type to build any experience you can imagine. With a custom skill, you define the interaction model.

Application APIs

Use our application APIs in your back-end service to receive customer requests from Alexa, and to tell Alexa how to respond. You can also use the APIs to personalize your experience, link customer accounts, sell goods and services, and take advantage of other Alexa functions.

Software Development Kits

Take advantage of ASK SDKs to reduce the complexity of your code. SDKs for Java, Node.js, and Python provide language-specific functions for common tasks, enabling you to focus on your skill logic, not boilerplate code.

Development Tools

You can use the ASK developer console or the ASK command line interface (CLI) to create, manage, test, and publish your skills. You can also integrate these functions in your systems with the skill management API (SMAPI).


You can take advantage of ASK analytics to understand what's working well and opportunities for improvement. ASK provides a wide range of metrics, including customers, intents, sessions, utterances, and latency.

Customer Engagement Tools

Customer engagement tools help you build a strategy to expand your skill's reach. Pass signals to Alexa about your skill's functionality for name-free requests or bring in customers from your owned and paid channels.
