I want to get all the Id value using Javascript. Hope you can help me with this. 

Sample JSON Payload for request: 

Verb: POST

Content Type: application/json

Sample Payload:

{

  "Input":

  [{

    "Id": 123,

    "emailAddress": "xyz@google.com",

   },

   { 

    "Id": 555",

    "emailAddress": "xyz@google.com",

   },

   {

    "Id": 767,

    "emailAddress": "xyz@google.com",

   }]

}

Which version of Apigee are you using?

And also, after you Extract these values, what do you plan to do with them?

Hi dchiesa1, just a requirement to create a mock response on a proxy. I manage to extract the values by using nested for loops. Thanks.
