How to oAuth Google API from Lambda AWS? : <p>I am building Alexa Skill for Google calendar. The client side code works as expected on local machine because I can authenticate the local machine using the link. But, when I deploy the code on AWS Lambda there is no way that I can authenticate as I cannot input code via AWS console.</p>

<p>I am getting trouble in setting up authentication of Google Calendar API 
when deployed on AWS lambda.</p>

<p>This documentation doesn't help much to me
