Ruby on Rails: Capturing JSON data from webhook?

I'm trying to understand how webhook works. My understanding is that its the ability to connect two different applications. If I submit a webhook with url

localhost:3000/receiver

to one application, and I have my application with a method

def receiver

end

I was wondering if I don't know what the callback is from the webhook would be, how would I capture data? How do I save any JSON data thats communicating with my application? I was thinking maybe save some file to see what the objects are, but I'm still fairly new and not sure how to capture JSON data?

Thanks

If you are sure that the webhook is returning a JSON, you can so something like this

data_json = JSON.parse request.body.read

  1. Sure, a webhook a is tool to sincronize two apps
  2. You HAVE tou know the structure of the incoming json, because you need to get the info inside

  3. By definition a webhook is sent by POST method, so you can capture it just inspecting the body of the petition, i.e.

    webHook = JSON.parse(params[:something])

Your would try with github web hooks and publish your app in heroku, the api is very well documented and there are many examples.
