Is it possible to receive webhook events in Web Extensions ?

[Rajakumar R I]

Hi,
     I am new to Web Extensions developemt.
     We got a situation where we need to get the webhook events from 
other domin in the web extensions itself. The other domain is not in our 
control.
     We get the web-extension's url using 
browser.identity.getRedirectURL(). We have registered this as the 
Webhook POST callback url in other domain.
     Is that possible to receive the webhook events whenever the other 
domain POST the data in callback url ?

     Intercepting HTTP headers are enough to get the data or we need to 
have Node moduls\Node Servers inside web extension ?

Thanks & Regards,
