We are thrilled to announce that starting today, Alexa skill developers can now send content to users in stages, using Progressive Response. This new capability helps you to keep your users engaged while a full response to a skill request is being processed.
Prior to today, skills developers have been constrained in their ability to send content, with skills required to wait for all processing to be completed before delivering any payload to the user. This left users waiting and wondering what was happening while skills processed their experiences. With Progressive Response, you can now use that time to inform, amuse, engage, and delight your users.
