Ruby on Rails: Capturing JSON data from webhook?

Question

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

Answer 1

如果您确定webhook正在返回JSON，那么您可以这样做

data_json = JSON.parse request.body.read

Answer 2

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, ie

    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.
