Question

Is it possible to trigger intent-B from the lambda function of intent-A without prompting to user?
Suppose user typed something and an intent-A is fired, after some proc

Answer 1

Yes it is possible .From the lambda of Intent-A , you can write the below code :

        intentRequest.currentIntent.name='Intent-B';
        var param1={
                slot-B:null
            };
            intentRequest.currentIntent.slots=param1;
          callback(elicitSlot(outputSessionAttributes, 'Intent-B', intentRequest.currentIntent.slots, 'slot-B'));

Below is the function for elicitSlot

function elicitSlot(sessionAttributes, intentName, slots, slotToElicit, message) {    
return {
    sessionAttributes,
    dialogAction: {
        type: 'ElicitSlot',
        intentName,
        slots,
        slotToElicit,
        message,
    },
};

}
