If you connect your devices to Alexa over the internet, you’ll use the Alexa Skills Kit and the Custom and Smart Home Skill APIs to build your skill. The Smart Home Skill API provides a built-in voice user interface that simplifies the process of enabling customers to control cameras, cooking devices, entertainment devices, lighting, locks, thermostats, and more with Alexa.
Test your skill's service using the Service Simulator. Simply input text, then view the service input and output on the screen.
Test your user experience using Echosim. This online community tool simulates the experience of an Amazon Echo.
Invite up to 2,000 beta users to test your Alexa skill and provide feedback. You choose the users and supply them with your smart devices.
