Summary

Is it possible to update the variables using a postback payload from a webhook channel?

Content

Hi developers,
I am developing a custom SDK for Hangouts Chat and I want to update the variables using Postback actions.
I referred to the official documentatiton and I am a little unclear of what needs to be done. 
Could anyone give an example of a message payload for Postback action that updates the conversation variables?
A full example is really appreciated. 
This is my code snippet:

 

let message = {
"userId": userEmail,
"profile": {
"firstName": "Bob",
"lastName": "Franklin",
"age": 45
},
"messagePayload": {
"type": "postback",
"postback": {
"variables": {
"name": "Sharath Chandra"

Howdy, Stranger!
