How to send Postback to Webhook using Launch Mobile Property?

[UserAP]

Hi all.

I have Adobe mobileSDK installed on the app, and here is the sample data sent to Analytics using track state:

data: {
        "state" : "e_pageview",
        "contextdata" : {
            "e_pageview" : "1",
            "ev_pagename" : "Product_Category_Overview",
            "ev_language" : "de",
            "ev_previouspage" : "Homescreen"
        }
    }

With this, I created a rule in Launch Mobile Property based on e_pageview state,

& action is a postback to webhook.

upon rebuilding library with rule and triggering track_state or track_action from mobile app, I should expect sample postback data to my webhook within few seconds, but no success yet. 

Could you please tell me if there's anything I could be missing here?

Thanks a lot.
