Retrieving information from a POST without forms in Django
A Django view doesn't have to use a form. Everything that was POSTed is there in request.POST which you may access directly. (I commonly do this to see which of multiple submit buttons was clicked).  
Forms are a good framework for validating the data that was POSTed, but you don't have to use their abilities to generate content for rendering. If the data is validated in the front-end, you can use the form validation framework to check against front-end coding errors and malicious POSTs not from your web page, and simply process the cleaned_data if form.is_valid() and do "Something went wrong" if it didn't (which you believe to be impossible, modulo front-end bugs or malice).
I'm developing something like an API (more like a communications server? Idk what to call it!) to receive data from a POST message from an external app. Basically this other app will encounter an error, then it sends an error ID in a post message to my API, then I send off an email to the affected account. 
My question is how do I handle this in Django without any form of UI or forms? I want this to pretty much be done quietly in the background. At most a confirmation screen that the email is sent.
I'm using a LAMP stack with Python/Django instead of PHP.
