Reset Alexa sessionAttributes

Question

At end of active session of user I wants to remove all sessionAttributes using handlerInput.attributesManager.

How to remove all sessions at end of AMAZOn.StopIntent

Answer 1

Alexa ends it's active session when there is no input from the user even after reprompt, or the response itself has a shouldEndSession set to true, or there is an error in the response. In all these cases the sessionAttributes are all cleared. So you don't have to explicitly clear it.

The user has open the skill again to interact with the skill and that will be a new user session with no sessionAttributes itself.

Now if you want to end the session which in turn clears the sessionAttributes you do:

In ask-nodejs-sdk v2, don't specify a reprompt, this will set shouldEndSession set to true automatically.

return handlerInput.responseBuilder
      .speak("Bye")
      .getResponse();

In ask-nodejs-sdk v1, use :tell, this will set shouldEndSession set to true automatically.

this.emit(':tell', 'Bye');

Answer 2

Here I found the solution,

handlerInput.attributesManager.setSessionAttributes({})

return handlerInput.responseBuilder
.speak("Goody Bye")
.withSimpleCard('', "Goody Bye")
.withShouldEndSession(true)
.getResponse()
