Alexa Skill - How to Retrieve Slot Value in Lambda Function

Question

I am developing an Alexa Skill with one Intent that includes a Slot with several possible values.

My slot is defined with "name" : "Channel", "type" : "LIST_OF_CHANNELS", and values

1. iqram
2. ingrid
3. phil
4. clyde

How do I retrieve the uttered slot value to use in my Lambda function? It's the "retrieve value of slot from utterance part" I'm looking to have answered. Thanks so much.

 // retrieve value of slot from utterance     
 var c = intent.slots.Channel.value; 

 // append value to end of URL that references API
 fetchEnseParse("/channel/" + c, function(body) {

 // continuation of this function is below 

Answer 1

var c = this.event.request.intent.slots.slotname.value

This should give you what you're looking for.

In the event that your lambda receives you can find it here...

{
  "request": {
    "type": "IntentRequest",
    "intent": {
      "name": "YourIntentName",
      "slots": {
        "slotname": {
          "name": "slotname",
          "value": "HERE!"
        }
      }
    },
    "locale": "en-US"
  },
} 

The event is passed to your lambda handler.
