I have a skill (currently in development phase) hosted in AWS. I want to move it to a local machine instead of using lambda function. I have written an API, exposed it with ngrok publicly and configured it as an endpoint to the skill. I am able to receive the request JSON object from the Alexa skill. But I am not sure to which URL or API do I send the response JSON to.
I have received an apiEndpoint and apiAccessToken in the request JSON. I have tried sending the JSON to the apiEndpoint but I got a 404 (I was expecting this as the URL did not have any skill specific ID but just gave a try). What all do I send in the JSON object and to which URL do I send it to?
Send the response back to the request you receive. Whenever you receive an API request you are supposed to respond back or acknowledge it. In Alexa, you will receive a POST request to your endpoint with a payload and you have to return a response in the expected format.
apiEndpoint and apiAccessToken is used to fetch additional information like device address and pincode.
