What is the right way to fetch data that is being automatically posted to the URL that I'm developing the app on in Django?
Depending on how the data is posted you will be able to find the data with 

request.POST.get('url')

or if it is not sent as JSON body it will be found within, which will need to be decoded manually

request.body
There is data being automatically sent with POST request to the address I'm developing on, in format of JSON string.
How should I properly fetch this data in my function based view, so I can manipulate with it?
data = requests.get(url).json() did not work for me, it gives me back this error:
django.urls.exceptions.Resolver404: {'tried': [[<URLResolver <URLResolver list> (None:None) 'en/'>]], 'path': ''}
At least, how can I test if there is any data being sent to the url?
I'm developing in production env.
