Alexa.Presentation 1.0

Note: Learn how to improve your skills with APL with Build visually rich experiences using APL at the Alexa Learning Lab.

The Alexa.Presentation interface extends the Alexa Voice Service (AVS) to report presentation states to AVS.

To learn more about APL, its interfaces, and how to use those interfaces together, see Alexa Presentation Language (APL) Overview.

Capability assertion

Alexa.Presentation 1.0 may be implemented by the device on its own behalf, but not on behalf of any connected endpoints.

New AVS integrations must assert support through Alexa.Discovery, but Alexa will continue to support existing integrations using the Capabilities API.

Sample declaration

{
  "type": "AlexaInterface",
  "interface": "Alexa.Presentation",
  "version": "1.0"
}

Events
