Use webhook response in the flows

1. Let's say you make a webhook call (by using the above steps) and you want to use the response variable in the flow.

For example, if you send a response like a below object

{
"success_message" : "You are onboarded.",
"status_code": 200
}

Please note that your webhook should always return a JSON object (not an array).

Then you can use that response as @results.mywebhook.success_message Or if you want to use any other variable then it will be *@results.mywebhook.YOUR_RESPONSE_OBJECT_KEY

Here my webhook is a custom name you defined on your webhook node and success_message is the key of the response object you send back in a webhook call.
